I am using Cmor-Fb-FC wavelet transform in matlab environment. Fb is bandwidth and Fc is center frequency parameters. with trail and error procedure I select Fb-Fc as 5-1, and I've got rational output. But I want to know whats the rule of selecting Fb-Fc parameters?I am using 300 samples over 30 sec. so my sampling frequency is 10 Hz.Here is my signal.
x=sin(2*pi*t*.1).*(t<10)+sin(2*pi*t*0.3).*...
(t<30)+sin(2*pi*t*0.6).*(t<10).*exp(-t*.1);

It depends how much overlap do you need between two successive wavelets. Or simply, how close are your frequencies. Basically, you increase these parameters to get a finer frequency resolution.
