Hi Subrat,
I understand that you are applying 'cwt' function to a sine wave and then performing 'icwt' and are observing some deviation between the original signal and the reconstructed signal.
In the code shared by you, a frequency range is mentioned for which the inverse continuous wavelet transform values are calculated, which resulted in a large deviation between the original signal and reconstructed signal. Consider removing the frequency range and observe the changes. However, note that there can still be some deviations between the original and reconstructed signals.
I hope this helps.
