How to get only envelope spectrum plot, not the envelope signal

I am using

envspectrum(signal,samplingFrequency);

To get the envelope spectrum. I just need to plot the envelope spectrum. How can I do that? Also how to modify the scaling?

hello

yes your are using the right function , but what is your problem ? the function does what you need...

I just want the bottom plot, preferably in a subplot. Also, I want to manipulate the scaling.

[Mathieu NOE]

so use the following form :

[ES,F] = envspectrum(signal,samplingFrequency);

for different scaling, it depends if you want to normalize to the highest peak or do something else...

for example, if the highest peak must have amplitude = 1

scale _factor = 1./max(ES);

ES = ES*scale _factor ;

then

subplot(....), plot(F,ES);

That was exactly what I was looking for. Thanks. How do I select your response as the best answer?
