Re: Removing DC
Hi Sridevi,
You can do it in two ways.
Way1: Just pass the signal through a highpass filter. (This will remve the DC),
Use fadtool to design very constrained filter.
Way2: (Normally high pass filter is not advisable)
Step1: You need to implement a low pass filter to extract the DC Component of your input signal. (You can use fdatool and design a very constrained filter, just allowing DC)
Step2: Then subtract the output of low pass signal from your signal.
