Goodmorning everyone, I plotted a scalogram of my signal (xa) in this way:
cwt(detrend(xa),600);
title('CWT of the acceleration signal');
The acquisition frequency is 600 Hz. The scalogram shows a maximum frequency (ordinate axis) of about 110 Hz. I'd like to show the frequencies up to 300 Hz such as in the FFT (the sampling frequncy is 600 Hz). How can I do it? Thank you!
