Understanding of cepstrum example

Colleagues, 

I am playing with Bearing time-cepstrum analysis.vi from advanced signal processing toolbox.

I am tryung to replace the default synthetic signal with my own, and generate 2D plot of cepstrum vs time.

Question is- I can not find a way to explicitly mark quefrency interval in which I want cepstrum to be plotted. 

By default, in TSA time-cepstrum.vi I can only set the offset ( starting point) from where it should be plotted, but not the range in seconds.

 

Can someone give me a hint?

Hello SParkhonyuk

 

   Since your request is about a missing feature that could be of general interest I've created a Lv2014 subVI that does what you need. Insert the attached subVI in your code as shown here.

    The default duration parameter value of -1 corresponds to full duration.
