we received mail from proffesor BC Joshi suggesting improvements in our receiver design. he suggested use of butterworth filter instead of simple RC filter which has a poor roll off. we read about butterworth fiter , cutoff frequency of filter. we decided to use butterworth low pass filter followed by butterworth high pass filter for our band pass filter design.
