I would like to extract a range of frequencies and convert them to time domain using inverse wavelet transform. But i could not do inverse wavelet transform for the continuous wavelet transform. Kindly help me out!!

> Hi Jet, are you sure you need to use the CWT to analyze your signal and not the critically-sampled wavelet transform (dwt) or the wavelet packet transform? Both the dwt and discrete wavelet packet transfrorms in MATLAB have reconstruction routines. If you still feel you need to use the CWT in your analysis, then there is a least one file exchange submission for you to consider:
