Frequency detail analysis of signals

3 views (last 30 days)
I am working on ECG signal and I need to figure out the different frequency components of it. Can anyone help me to analyse that using Discrete Wavelet Transform?
I am new to matlab. I have tried referring documentations for DWT and frequency analysis but couldn't understand much.
If anyone has worked on it and can help kindly do.
Thank you in advance.

Hi, You can use the fourier transform to get the various frequency component. The fft command in MATLAB can be used for this. You can refer the below example for more information.
