i have a 2 part question : why is the output of a sine wave ptbypt.vi so small? each data point is in the order of 10E-15 . basically i want to add a sine ptbypt waveform to gaussian ptbypt wave form. but as i apply probe i see that the gaussian data point are very much larger than sine data points i-e 10E-3 . the summaiton of the two is then fed into an fir filter ptbypt. the fir is part of my rls algorithm which is suppose to predict the tap weights and remove the noise. but the tap weights always remain the same irrespective of the fact input is purely gaussian or purely sine. so when the summation of the both is applied to the input and the filter , changing the standard deviation of the gaussian doesnt effect anything either.
if further leabration or cct is required please ask!.if someone knows what might the problem be, please help me out. ive hit a road bloack here. it would be very much appreciated! thankyou

Hi trusted47
According to the help file for this VI, its default amplitude value should be 1. Have you tried probing the output of this VI directly?
I can see that you have a control for the amplitud input of that VI, is this control being manually handled or is this the input of a SubVI?
Thanks!

yesh its manually handled. ive set it to 10.

Could you please upload your VI or a reduced version of the code where this behavior can be recreated?
