How to divide the waveform into small pieces (which have different lengths)

[muahang1234]

I have a long waveform which is just a combination of a waveform + 0 + another waveform + 0 +...I would like to have small pieces of the long waveform.  The problem is I cannot think of anyway to detect the 0 in order to seperate them.  Any hint would be appreciated.

How are the zero segments generated? Are they exactly zero or average zero but with some noise? Do you know the length of the zero segments? Is it always the same? Do any of the waveforms have segments where the real data is zero, and, if so, how long can those segments be?

My first thought is to use In Range & Coerce with limits just slightly above and below zero. The check the length of any set of samples not In Range.

Hello Lynn,

There will be noise (white noise) and the length of zero is variable.
