there is wavelet, fft etc.. but no s transform in the list.

The Laplace Transform (which I assume is what you mean by the s transform) is for continuous signals, and is usually used when dealing with mathematical (continuous) functions.  The analog for sampled (discrete) functions or data, which is LabVIEW's domain, is called the z transform -- you can find references to the z transform in LabVIEW Help.

Nope.  Good point.  However, when I searched "Laplace Transform LabVIEW", I found NI Application Note 39, Linear Systems in LabVIEW which discusses how to use the Z transform, including how to transform a Laplace Transform to a Z Transform.  I suppose it matters what the Poster wants to do ...

My snark was directed at the OP Bob.  It's pretty bad to not know the calculations you want to do.

The s transform is totally different from the laplace transform. Refer atachment.

Have you looked at STFT Spectrograms.vi in the Signal Processing palette?
