hello Sir ,

Sorry for disturbing again I have used the PtByPt Mean as shown below but its not accepting the inputpt.PNG

Hi Gowtham,

 

did you read the help for that mean function?

 

It does accept only scalar inputs so you need to place it in a loop to handle your Y data array.

And you should not reset it with each call as you do now.

I also used it to smooth the PSD output instead of its input data…

Hello Sir

I have done as per you said but still I'm not getting as yours output find the attached viptbypt.PNG

Hello Sir

I have to generate 0.2v of white noise so I have given Standard deviation as 0.2 is that right...??

You still reset the Mean function all the time and you filter the PSD input instead of the output…

Apparently not right when you look at your waveform graphs…

How do you define "0.2 V of white noise"? (Again: what is your exact requirement?)

Hello Sir,

Its like I want to generate a Gaussian White noise  of 0.2 Volts

Hi Gowtham,

 

I want to generate a Gaussian White noise  of 0.2 Volts

Please define "0.2 V": RMS, max amplitude, peak-to-peak? Right now you only set the standard deviation…

 

On your VI: it also doesn't make (a lot of) sense to set the windowd length of the RunningAverage to your array size! Did you read the help for the RunningAverage and do you know how a RunningAverage works? (Wikipedia might be a godd source of information…)

Best regards,

hello Sir,

I tried of smoothening the Noise after psd plot but the Psd output data is cluster of 3 elements so I thought of getting the waveform contents and then apply to the PtbyPt Mean but I am unable to get the Waveform Contents...??
