• Eliminate the peaks of measure

  Hello everyone.

  I have a problem with my VI. I need to measure a signal frequency. While I measure, I have a correct value, but after reset the elapsed time sometimes, I take a pic. I can't remove it. I almost am newbie in Labview. I'll be grateful for any help with this.

  Hello Lynn

  Sorry for my absence. I need to measure a frequency to simulate signals. (0 to 50 Hz frequency). All right, except that of the peaks. I can see a frequency in "Czestotliwosc. I count a Falling or Rising edge and calculate knowing his time. The elapsed time is a function of "Sync Windows" in this VI.

• What should I do to make my music release, I tried to restart my phone but it is frozen on the peak of Apple's music. There is no sign in or buttons to click and I can not get to any of my music

  Ive tried everything to unfreeze it, but it won't unfreeze. It is stuck on the peak of Apple's music and I can't go to my music at all. I tried signing in and out and even turn off my phone, but it does not work.

  Try double pressing the 'home' button and drag the application to the top music. Then hold down the sleep/wake and the "home" button until the Apple logo appears. -AJ

• filter the peaks on the signal from ECG pulse!, help!

  Hello

  I have RCV of the ECG signal. I filtered the ECG signal and get the resource (interval between each pulse of ECG) records.

  

  The source of the signal have noise I use a threshold but sometimes spikes of failure. Like the previous capture. Normally, if you get a pic of fault detected, I'll try to find this index to add to the left or right of the peak, normally I add to the lower value. This works if it has only a bad impulse between 2 good.

  The problem come when I have more than a ridge between the two coupons.

  Also, when the impulse of R a loss threshold I have trying to find the index and get 2 new reading making division 2 peak value.

  I have attached the method I've used to adapt it. I only works if I have 1 Ridge added on real measures of R or pulse 1 loss R, when I have several pics no work.

  I would like to hear an idea to make it work better. I don't like the idea of removing the value interval, I have 2 hours of reading and if I remove the values I have lower data outoput is why I tried to summarize or division of values to get the correct reading without losing any data.

  Perhaps, there is any better filter for ECG of entry, so I have a R-own pulse and less noise between ECG pulses.

  Any advice is welcome.

  Best regards, Fred.

  Almost.  in the last step, you have extracted the real part of the complex waveform.  Instead, you must retrieve the extent.

  

  BTW, this idea isn't mine.  I got from this article

• Change the peak of the sine wave in a time interval

  Hello

  I had a sinusoidal signal. With peak detection, I can get its peak and after he group thus places, I can get a XY chart that indicates the time vs pics. However, all the 10s, the pic will change. I would like to show the continuous change of vertices in that graph. However, even if I extended the x-axis (time), the PIC cannot change after some determined points. What I've got, it's the ridge line climbs to a higher or lower level. However, no continuous change is displayed.

  Because of the size of the data matrix? I mean, the graph updated every time after that it got a number N of data? Can I increase the number of N through buffers renovated or change N somewhere?

  Thank you.

  I noticed a few things: first, all displays are graphics and graphics is not the memory associated with them every time they are updating old content is completely replaced by new content. The way you describe what you want, you need a table somewhere to capture the peak each acquisition value.

  Second, you don't have a count by sampling wired to the acquisition of VI. Run in this way, the read function reads however many points is available - and sometimes this counter is zero. Try a constant with 100 inside wiring the number of input samples.

• How to calculate the signal / noise from the graph?

  In my current project, I read a periphera voltage signal. the signal lead noise even after filtering.  So, to identify the necessary data, I averaged the signal.

  I have attached the file with an image of graphics. In this graph, the recorded data are drawn black and medium online graph is plotted in red. Now, I have to calculate the ratio of signal to noise to specify with these peak values. How to do?

  As the signal passes through zero, be careful in the way you set the signal / noise.  For sinusoidal signals, that ratio is defined as the RMS value of the noise (the signal with the desired sinusoidal signal deleted) divided by the effective value of sinusoidal component.

  First of all I would like to subtract the average value of the raw signal.  The difference is the noise.  You can set the signal / noise.  A RMS calculation might work.  If you have a mathematical model for the desired signal, a fitting for this model can be useful too.

• How to calculate the polynomial graphic adjustment of waveform

  Hi all

  I am new to lab - view so would need a little assistance in one of the problem I have right now.

  My problem is: how to calculate the polynomial graph of waveform data adjustment? I need to convert the waveform to XY graph data, and then use the polynomial vi made integrated to calculate the fitting?

  Detail: My problem is that I have waveform graph, I calculate the vertices and the Valley, but because of the noise, my peaks and Valley detection is sometimes not exact, so to smooth the chart that I must apply the polynomial fit.

  If anyone can help me in this, I'll be very grateful.

  Thanks in advance

  Hi Omar,.

  have you seen the suggestion of Lynn above?

  You already have the values of Y (your table). Now, you need build the table of X as indicated, only to replace the value of dt with your spacing from point to point. Somewhere in your code, you know that the value that you have an x-axis indicated in milliseconds...

• Calculate the average per slot?

  Hi Chaps,

  I am a beginner on numbers (almost everything on Mac I would say) and I need help to calculate average values.

  These are calculated values (column 2) taken on a specific time of the day (column 1).
  I managed to create a third using a built-in function to get the time slot (column 3).

  14:58:42	235	14
  14:59:42	274	14
  15:00:50	7937	15
  15:01:55	5157	15
  16:02:57	1822	16
  16:03:57	207	16

  Can please somebody see me step by step how to calculate the average by time slot as below?

  14	254,5

  This can help you

  

  Assuming you data in a table named 'Data' and the information is summarised in another table (right) named "Summary".

  Select cell B1 in the summary table and then type (or copy and paste from here):

  = SUMIF(Data::C,a1,Data::B) ÷COUNTIF (Data::C, a1)

  shortcut for this is:

  B1 = SUMIF(Data::C,a1,Data::B) ÷COUNTIF (Data::C, a1)

  Select cell B1, copy

  Select column B, paste

  What program of worksheet that you are using? Since you have a newer iMac running El Capitan, I can safely assume that you use NOT AppleWorks, which is a Power PC application that can run on any OS newer than the snow leopard, OS X 10.6.8.

• How to calculate the difference between two times by the NUMBERS

  I'm so bothered by the fact that I can't understand that.

  Cell B2 - 08:00

  Cell C2 - 10:50

  (How can cell D2 - I get this cell to calculate the difference and say 02:50?)

  I know it's probably one of the most basic operations, but for the life of me I can't understand it. The cells B2 and C2 are formatted for a 24-hour clock. But if I tell the system to just subtract the two, I get "0,118. Everything I find on the forum search goes beyond what I need. Can someone help me?

  Thank you

  Hi sapirs,

  Departure and arrival of the cells are in Date and time with Date format: no and time: 24-hour clock.

  

  Formula in D2 (fill down)

  = C2−B2

  

  The results become a duration format, but under automatic (numbers automatically worth this format)

  

  If you wish, you can change the cells of lasting results.

  What Data Format have your result cells?

  Kind regards

• How to calculate the execution time of a SCTL in FPGA VI?

  Hello

  Can someone guide me that how to calculate the execution time of a SCTL for an iteration in the FPGA VI?

  Thank you and best regards,

  Rashid

  Hello r,.

  A SCTL will always run in a beat the clock it has been linked to.  So, if you use a 40 MHz clock, this loop will run in 25 ns.  If the code cannot complete in that, or if it requires two graduations of the watch to do the calculation, your code does not compile, then you have the guarantee that this will always be how long it takes this piece of code to run.
