How can i smooth my graph?

[madgreek]

hello guys.

i want to smooth out my graph so i can distinguish big peaks (pitches) in it from other spurious smaller peaks.how can i do that?is there a way to make it more visual easy for someone to see the big peaks or to emphasize even more the biggest peak?the graph shows the pitch period of a segment of a speech signal using the cepstrum algo.

cheers

My suggestion would be to perform curve fitting,  In function tools>> Mathematics>> Fitting you will find quite a few cure fitting vi's ( Linear, Exponential, general polynomial fit etc).

Here is a brief introduction to curve fitting
