Signal Frequency evaluation using Wavelet transform (CWT, Morlet wavelet)

30 views (last 30 days)
I have a signal (32Hz sampling rate) and I have to evaluate it's frequency using Wavelet transform. The most interesting frequencies are from 0.005 - 2 HZ and I want to evaluate their power...
I would like to plot a - 3D plot (frequency / time / power) - 2D plot
Please give me instructions to do that. Thank you!

Hi Marko, Do you have access to R2015b or later? If so, take a look at this example:

Hi one more time
in this article: http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=790500&url=http%3A%2F%2Fieeexplore.ieee.org%2Fiel5%2F10%2F17164%2F00790500.pdf%3Farnumber%3D790500 They say they choose scales between 0.5 and 200. The scale was discretized with sigma=1.05. scale 0.5 corresponds 2Hz and scale 200 corresponds 0.005Hz...according to scal2frq function, this frequencies are different in my case... How they get frequencies between 0.005Hz - 2 Hz?
