• How to get the normalizede power spectrum or spectrum of amplitude in laview?

  Hi, I'm recently analyze and compare the different beep power spectrum to various different sounds. In order to avoid the effect of the amplitude (which changes to different requirement, even for the beep even), I want to use the standard power spectrum or spectrum of amplitude standardized by deviding the power of each frequency components of total power of the sound signal at this time. So, how can I achieve this in labview?

  Thanks in advance

  What is the data type? If it is an array, you can just divide by the sum of the powers. This value can be designated independently, or you can just divide by the sum of all elements in the array (use Add the elements of the array).

• Spectral power sinewave AWR VSS level

  Hi all

  Could a good colleague AWR user wanting to help me with responding to a question concerning my use of a measure of the power spectrum - use of the SPECTRUM of VSS-> PWR_SPEC function?

  It's a simple question, but I think I need help from experienced users of AWR to help me.

  In VSS, I simply used a sine-source to generate a sine wave of 1 kHz with an amplitude of 1V (PIC)... in other words 2V peak-to-peak. Then I simply put this sinusoid through a real signal to the converter complex (R2C) module. And then I put in place two simple measures of VSS. A fair measure was to observe the time - the wave of the sine wave - to make sure that I was getting 1 kHz and 1V (peak amplitude). The other measure involved simply by using measurement of PWR_SPEC to look at the spectrum of the sinusoid.

  For a sinusoidal 1V peak, I calculate that the RMS 1/sqrt (2) amplitude. And if the reference resistance is 50 ohms, so I calculate that the power of the sine wave (Vrms ^ 2) / 50, which is 10 mW (IE 10 dBm).

  For the sine wave spectrum, I expect to see two spectral lines, one at 1 kHz with an amplitude of the component of 0.5 and a to 1 kHz (negative frequency) also of amplitude of the component of 0.5. In terms of power and with a 50 ohm reference resistor, then is the power in the component of 1 kHz (V ^ 2) / 50 = (0,5 ^ 2) / 50 = 5 mW. And the power of the component-1 kHz is also 5 mW. Thus, the sum of the power of these two gives 10 mW, which is what I expect because the total is equal to the computed RMS power above (in the sine wave).

  Now, in simulations of VSS, simulation results are indicating that the power of the component 1 kHz is 2.5 mW (i.e. 3.979 dBm). And also indicates that the power of the component-1 kHz is also 2.5 mW (3.979 dBm). So the results of the simulation, the total power is 5 MW, which is exactly half of the value I want.

  So for now, it seems that the levels of spectral power of the simulations of VSS components are always 3 dB LESS than what I calculate. So half the power is lost somewhere.

  Can I ask other users of AWR, if I set up the simulation properly (or not) and point me in the right direction? I think I'm just not using the Simulator correctly and just need some advice to put me on the right track. Or if I get things set up properly, then I'm missing an important step as the calibration for the measurement of another point of reference?

  SINUS block with a complex output, by default, uses the representation complicated envelope with a frequency equal to that of the sinus. So, if you place a measure of its output waveform, it will display a constant power of (1 + j0). The CTRFRQ = 0 setting will allow you to 'Center' of the signal in the DC and see a sine wave at its output. The spectrum of a complex sound signal will contain only a single tone to + value of the QRU. The two points to + FRQ and - FRQ, with 7 dBm power, each will be displayed only for a real signal if you view all frequencies in the spectral measure.

  You can find detailed information on this subject, as well as calculating corresponding, by doing a search on "complicated envelope representation" online. The main thing is that the complex representation of a sound signal will be A * [cos(2*pi*f*t) + j * sin(2*pi*f*t)]; However, when you use R2C you get only the real part, A * cos(2*pi*f*t), therefore half of the power you would get a SINE block with an exit node complex.

• HDMI plugged new spectrum HP i5, 4 GB, 128Meg, (WIN 8.1) on television, picture fine but no sound

  Hello.. HP G4X24PA #ABG spectrum, bought a few days ago links in via a cable HDMI to Sony HD TV - picture fine but no sound... tried the Panel, her etc, but no sound HDMI to click and be told by default?   IDT High Definition Audio Codec listed but no connection HDMI - suspects not updated drivers? But HP says it all assistant is updated?  Focused web - many answers for Win XP/Vista etc but I'm under WIN 8.1 - can always connect external speakers or use Y-connector but I think that this simple cable HDMI SHOULD work? Any help appreciated - first post please treat me gently (and as a new stupid nerd head please... that is to say the simple answers please...)!

  To solve this?   seems to not be the order in which the equipment is connected... first of all, cable HDMI plugged to the TV and computer, then switch to computer, then switch to TV... seems to work with the image and the sound from the TV every time until now...   (More, once I had to check "mute" left!)

• Spectrum 13D-3000: Sound LED (F11 key) does not work on Windows 10 1607

  Hello!

  After the upgrade to Windows 10 1607, I have a problem with the sound led (F11 key).

  It is now always red even if I turn on the sound (by pressing fn + f11 key) or by turning on the sound in the Windows menu.

  Before updating the LED becomes white when I turn on the sound. IDT Reinstaling driver did not help. What can you recommend to solve this problem?

  Thank you!

  Mykyta salvation,

  Thank you for your answer!

  The issue started after a recent update of Windows 10? If Yes, then I suggest a System Restore to before that point and see if the problem is resolved. Then, you can block the particular Windows 10 update does not happen. How to temporarily prevent a reinstallation of Windows 10 driver update.

• spectrum 360: no sound after windows update

  Hello

  As a result of an update to windows 10 for the anniversary edition, I had problems with the sound.

  It says the audio device not detected.  I uninstalled the audio drivers and reinstalled them and it will work, but after restarting the computer, it gives the same error.  Sometimes a reboot it will work again, otherwise have to reinstall again.

  I couldn't run constantly, so I restored windows on the previous generation and it works well again.

  Anyone had this problem or could fix?

  Thank you

  Thank you.

  I ended up doing something like that.  I uninstalled the program conexant himself and installed an older driver (9.0.57.0), and so far it has worked.  I got the driver from the hp support page.

  The new driver worked until a reboot, then had to be reinstalled again.

  I thank once again.

• No sound - HP Envy 14 spectrum PC 64-bit laptop

  I've updated my computer a few weeks using the HP Tune Ups and since then, I've lost sound. At first I thought it was because something was cut, and this was not it. I tried mutiple ways to get back the sound, but none of them does not seem to work. Can anyone help?

  Audio devices on the computer:

  Intel(r) Audio display

  IDT High Definition Audio CODEC

  USB Audio Device (most likely not the problem)

  There are several ways to address the issue.

  (1) a junk and brute force method called recovery.

  (2) is trying an appropriate operating systemMicrosoft fixit automatic for any audio

  (3) use the Windows system restore. and choose a restore point before that the problem started trying to go back to a point where no audio problem did exist as dated.

  (4) check the update log that keeps the tune-up HP. Remove the updates at a time based on when you think the problem started. Don't go too far back in the newspaper. Use Windows programs and features (in Control Panel) to display and remove the updates.

  I recommend starting with 2 # #4 and #3. Check for audio at each stage.

  Can you post what OS is installed?  It would help greatly if you could provide a screenshot of the device (with audio devices expanded) Manager and the Control Panel window (like in the following pictures)?

  Hello

  I have a new spectrum x 360 (edition i7). I turned on the startup password in the BIOS and now (like your other models of laptop, it seems) we hear a beep very hard to start. I need the BIOS password for security reasons.

  I am running the BIOS that came with the machine (F.04) and there is currently no update the BIOS on your support page.

  I ask you if you can please provide a version of BIOS that allows the option disable the loud beep (or one that eliminates it entirely). I wouldn't return this laptop also easily avoidable problem.

  Thank you.

  The following BIOS update should allow you to exit the beep of password:

• spectrum of HP x 360: another device/Sound Card does not properly

  

  My card failed bodyguard. I can restart my computer and it works perfectly for a random duration. But usually I'll run youtube or soundcloud and the audio will just stop. The video will stop and play more.

  I try video files on my computer and they will not play on Windows Media Player. I try it in VLC and the video will play, but not the audio.

  I tried all drivers known to the process of the HP driver update, I tried to update the Intel Bios Chip, everything.

  I'm out of options. Can you help me?

• Spectrum Analyzer?

  Hi all

  I am looking to invest in a DAW for audio work (obviously), but I'm torn between Logic Pro X and Adobe Audition CC. I'm not a fan of the Adobe subscription model so I would invest in LPX, but the problem is that I can't find the function that I need.

  Adobe Audition CC has a Spectrum Analyzer and allows me to eliminate noise from my soundscapes, but I can't find the feature in LPX. Y at - it to download a plugin or a way to do this? I don't do music production, I am more than a sound designer for the theater and cinema and use recorded sounds so clean and restore is more what I'm looking for. I am rather new to this and would like any input you can provide.

  Thank you!

  I've been a user of the logic for many years, but I use Izotope RX as a plug-in (s) in the logic for a serious cleanup work.

• X 360 spectrum: spectrum HP x 360 under linux

  Hi, I bought a new HP spectrum x 360,

  For my work, I have to run the simulation trought OpenFOAM is easyer for me to use Linux.  Almost everything works out of the box, except one... sound thing.  I post a bug on launchpad, here the link:

  Spectrum of bug Hp x 360

  Like almost everything that you want to debug the phenomena. I know that you have not officially support linux on this computer, but it would be fun to be at least compatible linux.

  Thing I know:

  There was a bug that really resemble this one on the Dell XPS 13. The bug was in the bios that was setting his alternative map that did not work. In my opinion, is the same thing here. I need to find a way to tell the bios to load everything as if it's windows 8.1 (Yes, I just don't ask for any special treatment.)

  Thank you

  I'll give you all the support you need. I really want to fix this bug.

  PS: (HP if you correct this bug you will sell more than three of these computers, they all want one in the lab!)

  Follow-up:

  It looks that we now are hable to use mode strives of the sound card. It is good, but not perfect. The fix for the i2c will come soon, last kernel code ask a file mysterious drivers that does not currently exist in the directories of the linux firmware. Therefore, this case is closed because the only such issue. Follow the improvement furter launchpad bug.

  * THE SOLUTION CAN NOT BE THE SAME FOR YOUR DISTRIBUTION *.

  Of Spano:

  If you use gummiboot , you should have something like this:

  options acpi_osi ="! Windows 2013 ' acpi_osi ='! Windows 2012 "acpi_backlight = vendor root = / dev/sda2 rw

  The solution to the title of this post is for Debian-based distro. I'll put the solution for the other activities of distribution on this post, if they are on the forum. (You can't find it? Adjust the solution to adapt to your distribution and post-its, you make people happy )

  I SOLVED IT!

  After hours of pain, I can now use the integrated sound card with headphones, as well as the internal speakers.

  How to:

  Change grub config by:

  'sudo vim/etc/default/grub.

  Change the line:

  GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash".

  TO:

  GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash acpi_backlight = vendor = acpi_osi'!" Windows 2013 'acpi_osi ='! Windows 2012' "

  Then run:

  'sudo update-grub ".

  Restart twice.

  BOOM! The sound works in the headphones. The sound card is now in mode HDA (not I2S).

  To confirm, run:

  "aplay-l" and make sure that you have the following in the output:

  "map 1: PCH [HDA Intel PCH], device 0: analog ALC3242 [analog ALC3242].
  Subdevices: 0/1
  Subdevice #0: subdevice #0 '

  I use the Linux kernel spectrum 3.19.0 - 21-generic #21 - Ubixuntu SMP on Ubuntu x 64.

  EDIT: Even the speakers work, they have just muted in Alsamixer. Hallelulja!

• Spectrum of HP 13-3004tu Ultrabook: video playback choppy after you install the latest video drivers

  I upgraded my video drivers (Intel high definition (HD) Graphics Driver 10.18.15.4248 place) for my Ultrabook 13-3004tu of the spectrum and after reading so online video (YouTube, videos on the sites of integrated information ect) play jerky and the sound is distorted. He was going well until I downloaded the new driver.

  Hello @kiwifruit28,

  Welcome to the HP Forums!

  I have read your message and understand that after updating the graphics driver, your spectrum HP 13 - 3004tu Ultrabook there are problems with the video playback. Here is a document to help solve this problem. Here is a link to HP hardware Diagnostics where you can test your hardware for portable computers. Alternatively, you can do a System Restore to a point before the end of the update of the graphics driver.

• Spectrum of HP x 360 13-4003dx: support site of problems with 3.5 mm headphone and mp3 playback and no driver on the HP.

  Problem started when I could hear sounds watching videos, for example, Netflix, but couldn't hear during playback of music, for example, MP3. As I was trying to shoot of boredom that I realized that I couldn't hear anything with the headphones plugged into the headphone jack 3.5 mm. Then I discovered that the hp support site has all the drivers for my model spectrum.

  I followed the instructions listed here... http://support.HP.com/us-en/product/HP-spectre-13-4000-x360-convertible-PC/7527520/model/7791774/doc...

  but nothing has fixed the problem. To the best of my knowledge, I have all the latest drivers from Realtex and Intel. There is no driver option Microsoft High Definition Audio "generic" indicated in the list of drivers on my computer and I didn't understand how to get a.

  Can anyone help?

  @Jim0505

  Thanks for the reply,

  I did some research and found this link contains driver HD Audio Windows (generic), although this is not necessary if the drivers realtek audio have already been updated.

  If the helmet works on another device and still does not work on this computer, it is possible port is faulty.

  I would recommend that you get it repaired or replaced by HP support by phone:

  HP technical support are available by clicking on the following link:
  
  http://h22207.www2.HP.com/us-en/?openCLC=true
  
  (1) once the page opens, please select the country in which you are located. Then enter your model of HP on the right number.
  
  (2) then choose "Contact the Support" tab at the top and scroll to the bottom of the page "HP Support - contact" to fill out the form with your details.
  
  (3) Once finished, click the "Show Options" at the bottom right.

• X 360 spectrum: spectrum HP x 360 with Ubuntu: plug headphones is not turn off speaker

  Hiya,

  I just installed Ubuntu (Willy Werewolf) on my HP spectrum - most of the stuff worked right away, and I'm super happy with it. My biggest problem I've been struggling with is the sound: speakers are working perfectly, however when I plug in my headphones, sound is read through both speakers and headphones.

  I checked the levels in the mixer and the system is noticed when the headphones are plugged and turns down the speakers correctly (as in alsamixer) channel - it's just that seems to have no effect on the physical hardware. If I change the helmet, that the effects of the volume in the speakers and headphones.

  What is interesting, is that, when the headphones are connected, the speakers disappear in fact from the control panel and console announcements mark as "unavailiable. As the system seems to be doing things right from the software point of view, I guess that's maybe a driver issue?

  If anyone has seen anything like this before, any help would be appreciated.

  Thanks in advance

  Also the small LED F6 lights when I cut more, but I can't live without that I don't really like (but if anyone knows an easy way to disable this market / stop via the comand line, I get a script to do).

  Thanks for your help Hüffer, I finally found the issue myself.  This has proved to be a problem with the map pins (two or three pins speaker have been put to use the headphone output rather than the speaker output).

  If anyone has this problem, I used tool HDA-Analysier of ALSA to debug it and make the required changes pinmap. I fixed the problem by changing the following:

  0 x 17 to Audio output 0 x 11
  
  0x1D to Audio output 0 x 11
