I have a time domain signal from an oscillocope. I want to remove the dc offset in this signal. How can i perform this?
any help would be much appreciated.
I have attached the time domain file.

There does not appear to be a DC offset. Your signal oscillates (apparently saturating the amplifier for the first three oscillations), then converges to 0 in the end.

Hi,
You can use FFT and high pass filter to block low frequency component. Follow the link given below for more information on FFT using MATLAB.
