Hi,
I want to use CWT to modify the amplitude of signal in frequency domain (in a specific frequency band) and then reconstruct the signal. I want to do it by changing the wavelet coefficients at that band. Is that the right way?
Thanks in advance for your help.
Best,
Behrang

Hi Behrang
Yes, changing the coefficients of the wavelets is the right way for modifying the a signal.
You can follow the below detailed steps to modify the signal:
