I wanted to design a butterworth bandpass filter for photoplysthemograph signals.I have bandpass and stopband frequency values..I know I need to know the passband and stopband ripple values too...but how can I calculate them when I am not sure about the order of the filter? Can the order of filter be chosen randomly?I am sorry I am new with the filter desgning process
