• How to perform the FFT on medium thanks to the accelerometer is correct or not?

  Hello

  I do FFT on medium thanks to the accelerometer, but display is not correct? Can someone help me solve this problem. I use PKI accelerometer and connecting to NI WSN NŒUD 3202.

  

  

  What is the purpose of feeding one of the TFF to a chart with each iteration of the loop? You have found the spectral components different FFT of different sets of data. The graph of the whole picture emerging from the FFT.

• What does not restart in the FFT functions way?

  Hi all

  I would like to know what that "restart average" made for the FFT functions. According to aid,"reboot on average indicates if the VI restarts the process chosen medium." If restart on average is set to TRUE, the restart of the VI the selected with an average of process. If reboot on average is set to FALSE, the VI does not restart the process chosen sprawl. The default value is FALSE. When you call this VI for the first time, the averaging process restarts automatically. A typical case when you need to reboot on average is when a major change of entry occurs in the middle of the averaging process"

  I realized that the FFT function takes in an array of values and perform the FFT on it. If the FFT function keep a buffer previous values and clears when restart average = true? Because the FFT functions are not Point by point and they take both in all the data to deal with, "a major change of entry occurs in the middle of the averaging process" can be true?

  Thank you!

  Sigh.  I really tried to explain what was going on (probably) with this function, you use (and, I thought naively, you understand), but you got me wrong.

  

  This VI creates a zero average noise signal, providing 1024 points per second.  Do you know what should be the power spectrum of the signal?  Due to the randomness of the input signal, the power (for a small finished sample) spectrum will also have a random component.  If you had several ghosts of power on average, the average would begin to converge with the expected for random noise power spectrum.

  If you run this VI and look at the Spectra resulting (on average), you will notice that the first spectrum is the most "spice" and that spectra are averaged, the variation is reduced and diminishes the value of crete (shown by looking at the scale of Amplitude).  At any time, you can press "Reset average" and see this... reset the average, the following spectrum shows the growing nose, etc.

  It shows the right way to test the function of the power spectrum and discover what he does. My suggestion as to what makes this function seems to be largely correct.

• How to perform deconvolution using FFT

  Hello everyone

  Is there anyone who knows the algorith or can give me a vi that shows how to perform deconvolution of the two functions by using the FFT. Using labview for deconvolution, the suggested algorith is.

  1. Calculate the Fourier transform of the input sequence X * Y.
  2. Calculate the Fourier transform of the input sequence Y.
  3. Divide the Fourier transform of X * Y by the Fourier transform of is. Call the new h sequence.
  4. Calculate the inverse of Fourier of h to get the deconvolved Xsequence.

  I tried to do e same but did not work. I enclose a Vi in first, I bypassed a pulse-to-pulse-triangular square. Then I deconvolutee the convoluted signal using a triangular pulse with deconvolution tool in labview. Then, I tried to do the deconvoltion using the FFT algorith but did not work. Y at - it someone who has an idea on how to perform deconvolution using FFT.

• Low power mode will affect the performance of the camera?

  I take my iPhone 6 on a trip backpack my camera. I intend to put the phone in airplane mode and I wonder if I should also set low power mode. If I put it in low power mode, it will reduce the performance of the camera?

  I suggest that you test this configuration by yourself before you leave.

  You can also consider taking the external battery back up like those manufactured by mophie.

  I tried to figure out if I can update my graphics card and I was wondering if I could, and what graphics card would be better for my laptop for high performance on the game.

  Hello

  No, it uses the CPU/processor AMD Quad-Core APU A6-6310 2.4/1.8GHz:

• Performance of the fans on Satellite L30-134

  Hello

  I have a question about the performance of the cpu on my L30-134 fans (celeron M 410 @1. 46 ghz). Some users posted similar questions on different laptops series L, but I'd love to hear some comments L30 - 134 user/advice.

  The problem is that by default, the fan does not work on the down low all the time, but it is off and goes on every 2-3 minutes hit RPM high and causing a lot of noise. Sometimes however it works down low most of the time, being really quiet and keep the temperature at 48 to 55 degrees, while during for turning on and off the temperature is 58-65.

  There are two options for cooling in Toshiba Power Saver (which came preinstalled) we're max performance, the other is to optimize the battery. The fan seems to work on the Tower on / disable system regardless of the option selected.
  
  Q1 Do these two options are actually on the fan is constantly working on low speed or activation and deactivation?
  Q2 How can I do the fan runs all the time at low revs?
  Q3 is there third-party security programs to control the fan speed?
  
  PS: I don't have all of the options on the fan speed in the BIOS

  I'd appreciate your comments. It is not fun to have a noisy fan :)

  Hello

  As you have already mentioned the Toshiba Power saver is preinstalled on your device.
  My phone supports also this utility and energy saver controls the speed of the CPU and cooling mode.
  M unit fan starts to turn if the temperature rises to a higher level, but it depends on the use of the laptop. I don t play much games performance, but I use my camera for graphic design. Sometimes, the fans run really fast and long, but sometimes the laptop is quite.
  My support of intelligence tools speed level 4 CPU processing power and cooling method is the value max performance.
  I think the cooling also depends on the environment

  Moreover, I also read a lot of reviews on the cooling fan rotation and. Sometimes, the update of the BIOS changed the performance of fans

  A small comment to Q3: Don t think that any 3rd party application will control the performance of the fans properly. If the energy saver is not installed on the device, the power of Microsoft options are responsible for execution.

• Re: Satellite L500-19Z - how to increase the performance of the game?

  Hey

  Basically, I have a Toshiba Satellite L500-19z, with chipsets Intel Series 4 express. I know this isn't a particularly good game, but surely the performance of game should be reasonable?

  I get 80% of the time lag - while on my old laptop (which costs no more than £200) I could play World of Warcraft on it no problem (I played the Sims3 on this laptop and had very few problems. I'm playing Dragon Age, but it is almost impossible.) My laptop is not more than 8 months old.

  I just want to know if there is a way to increase the performance of the game? I thought that maybe to connect my laptop to a PC Tower, but that could lead to the worst game performance, so I said.
  I'm sure I can't replace the graphics card, I've updated my drivers, defragment disks and so on.

  Any help is really appreciated, thanks in advance.

  Hello

  Is there anything to do to increase game performance. It depends on the graphics card and Intel cards are not designed for games, they are a good choice for mobile use because they don t need a lot of power.
  In addition, the peut t graphics card be exchanged, s thereby.

  It s always depending on the game that you can play. Therefore, check the system requirements of all the games you want to play and if your graphics card is supported. Not all games support all graphics cards.

  You must also use low graphics settings in each game. You can use the parameters of t.

  For example on my Satellite U400, possessing the same Intel graphics card, I can play Half Life 2 which has already 5 years but always low medium graphics settings.

  Hallo,

  After paying a lot of money for this laptop, it's actually only worse typing Word-texts. There is almost no games that could be played on this laptop, nore wether Fifa 07, Fifa 08, wether Call of Duty 2 nore Red Orchestra (this list is in fact muuuuch longer), most of the time its simly to slow down. graphikcard 512 MB is not a lot if you cann't play anything.

  One question;
  Are you using Vista on this laptop?
  Well, if you bought this phone especially for a game I recommend the installation of Windows XP with the latest graphics drivers and then to try to play all the games.
  As you probably known t the Vista operating system needs a lot more material resources like old operating systems from Ms. This could have a bad influence on the performance of the game.

  Also I recommend you to check this page.
  078 http://www.Computerworld.com/action/article.do?command=viewArticleBasic&articleId=9011 & pageNumber = 1
  On this page you will find an interesting discussion about the game on Vista OS

  _By the way; _
  Microsoft has released a published and patch which solves the problems with the use of virtual address space. This is a reason why some games is crushed or didn't run smoothly on Vista OS

• Performance of the Satego P100-491 and 490

  At the moment I really disappointed of the performance of the portable computer game, but it would be a point to check with a
  installation of XP for the boarder that is due to the new vista!
  The problem is that I have a breakdown of the frame after a few seconds of the game, it seems to be related to the noise
  out, but I couldn't find any new drivers that the video driver date is December 2006 and the driver audio Nov 2006!

  Even on the nvidia site, there was no possibility to download a driver for vista and the series Go7X!
  Any thoughts would be nice!

  Even the same performance may be approved by the utility of radar of Toshiba it self it seems to be a Direct3D application and if you start it when its starting to animate and you move the mouse in a circle, you can see a hit on performance which is related to the video card/driver/hardware!

  It's a real mess, I opened a gives support to Toshiba speech on samedimidi does not have any answher. IM really surpriced I thought always to...

  Satego P100 unknown to me, but I presume that this laptop is similar to the Satellite P100. I can just recommend you to check all the processes and substantive services and put an end to all things, that you don't need.

  I put t know which antivir application is preinstalled but it's probably Norton as on other laptops Toshiba. Try to stop it or even delete the system and see if the laptop works better.

  By the way: is this model of laptop available in Germany?

• Improve the performance of the Satellite L300 graphics software and games-Vista

  After the first post on how I was disappointed with Toshiba L300, I found a solution for his performance on the use of software such as Photoshop, Corel and games like Warcraft III, NFS Pro Street, Titan Quest, Devil May Cry and so on. This tweak was found on another forum and was modded with the new driver of Intel and Toshiba L300.

  I would like to share with you all so that you can be happier with your product. This can be applied to other * X 3100 * computers:

  * Steps: *.

  1. download the latest driver from Intel (at the moment it is 15, 9 - 7.14.10.1472 at the link: [http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=2800&OS FullName = Windows Vista + * + 32 & lang = eng & strOSs = 164 & sub mit = GB 21%])

  2 extract the file somewhere on your hard drive.

  3 install the driver manually from the Device Manager (we can not update automatically as there are problems between the pilot back to Toshiba and this)

  4 Download this registry key to link: [http://www.mediafire.com/?4cejjqbmlm5] on your hard drive

  5. open this file with * Notepad *.

  6. research * game1.exe*

  7. you will see 4 lines, that I created. Replace the two * game1.exe* by the name of the Executive program, you want to give
  -For example: I want to improve performance for WarcraftIII, replace * game1.exe* by * warcraftIII.exe*

  8. add more software that require high graphics performance by adding a line more with * "_software.exe" = dword:00000001 * and * "~software.exe"=dword:00000001*

  9. save the file and apply the registry key by double-clicking on it. (Right of the administrator is required)

  9 turn on the software, and you will see that it will work better than before.

  I na? don't know if this has been posted here or not but hope that it is useful for the x 3100 and Vista users

  I'm happy to answer any questions. If you find the best methods, please share.

  Best wishes.
