How to remove DC offset in Matlab?

ft = fft(timeDomainSignal); % Tranform the original signal. ft(1) = 0; % Eliminate DC component so there will be no offset to the signal in the time domain.

How do I remove DC offset from data?

To remove DC offset, load your audio file, select the problematic area (or none if you want it to affect the entire audio), go to the Effects menu, and click on Remove DC. That's it; your audio should be fine now! What is this?

How to remove DC value from a signal in Matlab?

Method 2: Data_fft = fft(Data_with_dc); Data_fft(1) = 0; Data_without_dc = ifft (Data_fft); I think the first component of signal's FFT is actually the mean of whole signal and it represents signal amplitude at zero frequency, so by making it to zero, we can remove DC component.
