Chris Thank you very much.
#In my view, FIR filter can design by window function(fir1) , Frequency sampling(fir2), Parks-McClellan(firpm), fdesign(matlab toolbox) , etc. I correct ?
# If I want to design FIR bandpass filter for noise cancelation in ECG signal.
Could you tell me when we use "fdesign" ? what the difference for other function?
I very confuse.
