How to extract different frequency bands from the signal using CWT.
By using DWT we can decompose the signal with the help of low pass filter and high pass filter. Based on the requirement we can choose particular filter output. Please provide how we do the same thing for generating subbands using CWT (Continuous wavelet Transformation)
Hi Venkata,
it is similar when using the CWT - each scale you compute corresponds to a frequency (actually a range of frequencies and one "center" frequency). If you are using matlab the command scal2freq might be helpful to determine the frequencies which belong to certain scales.
However, you should be aware that not all wavelets are "compact" in the frequency domain, i.e. although a scale has a belonging center frequency it might include a broad range of frequencies).
Greetings, Sebastian
