• With an average using the "basic DC/eff' VI

  I seem to end up using the "basic DC/eff" VI a little average my data to my DAQ system. However, I have a question about what's going on "under the hood".

  Let's say, for simplicity I acquire data at 1 kHz into blocks of 1000 samples.

  Thus, all the 1 second I push 1000 samples in the VI-DC/RMS database as a data type of waveform.

  This means that the outputs 'DC' and 'Eff' will update at the rate of 1 second.

  The question is, is "continuous" averaging? In the sense that if I was doing 'good' low-pass filtering (on average is just the same as the low-pass filtering) - say simple TREE with notches n - to the DSP, then the output of the filter would be updated at the same speed as data entry; That is to say. taps would be 'move along' the input data at the same rate as the input data passes through the filter. I'm guessing based on my above explanation that's not what's happening. Instead, the VI DC/RMS is on average an entire block of 1000 samples and then 'jump' 1000 samples along and doing the next block.

  This is not necessarily a problem, but it is not not true low-pass filtering and I can image some scenarios where there might be artifacts because the moyenneur filter jump 1000 samples whenever it takes on average. I assumed that the only solution is to implement filtering in a loop of much higher speed and this could prove problematic in the higher frequencies of sampling.

  Anyone got any ideas on that? I worry about anything?

  Hi Dave,.

  The 'average base DC - RMS' feature is designed to work only with continuous acquisitions, it will lift a warning is the signal is not continuous. When you open the function and examine the code in the function there is a Subvi with status information, which permits the function to continue the average of the previous data block.

  For this reason, we provide a reset terminal if you need 'forget' the previous calculations.

  Much of this is discussed in the detailed help on function, but still sometimes there hands dirty to know how the code works and review the code.

• Unable to get the basic unit of the stainless steel bracelet

  Hi, I am unable; e of pop on the basic unit of the steel stainless bracelet body. I couldn't find anything online that shows the process. In addition, can I exchange the strap metallic with leather and other straps? where can I buy these? Concerning

  Hey!

  I understand that it may be a little difficult to understand, since there are no edges or cuts to adjust to pop the base unit on. I took a few photos for you:
  
  Basically what you need to do, it's only gently but firmly push you down on the screen next to the edge to pop out. Make sure it is on the same side as the microUSB port, you recognize there is not not a small hole in the front (and a microUSB on the back port). I've marked the photo that I took with the green as to where you have to press on and red on the side that you should not press.

  Once jumped, it will look like this:
  

  Let me know if is not yet known!

  About yew, you can exchange the strap, it's quite possible. Everything just to get a different bracelet and insert the base unit. Unfortunately, I can't help where you find it as it varies depending on the market, but see if your retailer can help you in this regard!

• Help to understand the basics of the integration of Javascript/QML

  Hey all!

  I am just development of BB for the first time, so please bear with me. I'm not sure that understand the interaction between JS and QML. I understand that you can write JS in QML, particularly in managers of signals, and I used chunks of it with success. Also, I show/read by the "Javascript in QML" and JS linked in the pages of Qt, which helped a bit.

  However, I am having a few problems incorporating it into my code.  Could you take a look at this and point me in the right direction? (I'm also new to JS itself, so maybe that my mistakes are with this instead?)

  }

  Return to the guideline;

  }

   

  
  Thanks in advance! I feel I'm missing something incredibly small/basic

  try calling it without braces.

  You can also create a function directly in QML, no need to export to a js file unless you want to use other components (that are not subcomponents) as well.

  to learn more about the construction of Qt/QML parent, I suggest to read this doc API:
  http://Qt-project.org/doc/Qt-4.8/objecttrees.html

  createObject (this) would create a new component with the parent defined on the object class, and if this is destroyed a new is also destroyed. This is useful when you create components dynamically as you don't have to delete them manually later.

• Series 2: Push the water

  There will be a way to push the water through the speaker without start/end an exercise (swimming)? An App? Maybe I wear the watch in the pool/shower or just wash my hands with a lt of water.

  "If air pushed by the speaker can get out, the water will be. So the speaker vibrates to push the air out, forcing the water out too. The user can turn the digital Crown to achieve, as a representative of Apple showed me yesterday. »

  When I click "Try Standard Version Anyway" it works, but for some reason, Gmail is say that Firefox 8.0 is not a modern browser. Also, whenever I visit Gmail, he returned to the basic HTML version... ba.

  It seems that Google is trying to make you switch to Chrome. I would stick with Firefox, but Gmail is an important part of my browsing...

• What is the best way to get back to the basics with apple products

  I have four devices apple, IMac, IPad, iPhone 4 s & a Mac Book Pro.

  I have problems to understand all of these devices in one way or another that I just are not / can not understand the jargon associated with trying to use to update or modify my needs.

  For example the iMac that I bought at the beginning of the year, I have a separate hard drive, I realized is not password protected, I downloaded the software of Lacie hard drive manufacturing, but I do not see that it works or what to expect, I thought that to have access, you will put in a password like I do when I turn on the iMac not so simple & I lost a whole day on this & finished frustrated as no further, this is the case every time.

  I need some tips on where to start because I don't have anyone to ask what do I escaped my way through.

  I think I need to get back to the basics & get a form any order that these devices are all different but have a purpose.

  Can someone advise on where I should start it please.

  iPhone iOS 7.1.

  iPad iOS 9.2.

  Book of Mac Pro OS X 10.9, Mavericks (I think)

  IMac Yosemite 10.10

  The most important thing you can have right now are backups of your important data.   Which is often using an external USB drive and a tool called Time Machine to back up your Mac and using the service cloud either Apple or iTunes for backup of your iPhone and iPad devices.  (There are other ways to make backups, but Time Machine is a common choice).

  To learn more...  Apple puts at your disposal a web site the basics of the Mac who could help with this (and similar sites for learning iPhone and iPad), there are electronic books available for iPhone and iPad too and most Apple stores have workshops for Mac, iPhone and iPad which may help.   There are also a few books available if you prefer.  Suits you depends on how you prefer to learn.

  Apple has built into recent versions of OS X called FileVault 2disc encryption.  There is no need of software add-on for that.

  If you are not sure what version of the OS X software you use or which specific Mac you use, then you can use  > about this Mac.   That will show you the General information on your Mac, and - as you become more familiar with this and need of more details, you can ask for more details here.

  Yes, there is a huge amount that you can choose to learn and use with any one of these products, if you want, or you can choose to learn enough to get what you want to do.   It is entirely your decision.

• Configuration of the basic Source of time to master for the 9234

  I have several cDAQ modules I use to collect data.  I use vi to Write can Express to save data to a file of PDM.

  When you examine the recorded data files, the measured data from NI 9215 provide pleasant timestamps to match how the DAQmx task has been set up--delaying the sampling frequency of 1000 with a 1 ms in the While loop.  However, although in the same vi - different tasks, but the same while loop - horodateurs of the NI 9234 do not correspond to the task of DAQmx implemented - sampling frequency of 1000 with a 1ms delay. After reading the material provided with the NI 9234, I found that maybe the machine clean master Timebase Source. There were documents that says he can be configured to be originally of Timebase of Master for the other modules:

  Configuration of the basic Source of time of the master for the NI 9234 (Interface FPGA)

  It is desirable to have the timestamps for data measured across all modules to match. We do not have the FPGA Module for LabVIEW. Is there a method in LabVIEW for all modules use the same master time base Source?  I assumed that because all the data collection has place in the same while loop by using the time delay of 1 ms it was forced through the code. This hypothesis seems incorrect from my review of the PDM data files.

  The NI 9204 provides a trigger only.

  Hi MgDAQ,

  An important concept to note is that the 9234 uses a delta-sigma converter and a clock of oversampling to read analog data. There is an inherent delay of entry due to analog and digital filtering built-in. Since the 9215 has a lower resolution there will be a lag the 9234 and 9215 finished. I've included some resources below:

  What are the for the NI 9233, NI 9234, and NI 9237 valid sampling rates? : http://digital.ni.com/public.nsf/allkb/593CC07F76B1405A862570DE005F6836?OpenDocument

• Digital output frequency seems to be twice the frequency generated by the basic function generator

  Hi Labview forum,

  I wrote a program (attached) Labview to generate 3 PWM, square wave, signals that has the same frequency and phase delay right (so that when a signal is off, the other signal is lit. Then the next signal). Everything seems to work fine except that the frequency of the PWM signals generated seems twice as the frequency given to the basic function generator. Anyone have any idea why this is happening? Anyhelp would be greatly appreciated.

  Thank you!

  Totally agree with the advice of all GerdW than the hardware timing of your hardware DAQ will be much more reliable.  That said, part of what you are probably hitting is a little quirk of the primitive delay msec.   Requests for 1 msec have long been particularly little reliable (although they * seem * to have improved in recent years, probably due to the better OS support in Win 7 or something).

  I did minimal mods to your code with comments from you switch to a timed loop.  My quick test showed he is good enough to hit the 1 length of loop of target msec.
