Abstract :
A new recursive algorithm for the impulse response coefficients of a FIR lowpass filter is developed. The algorithm is obtained from the differential equation for the amplitude response of a lowpass filter. While the original filter exhibits maximally flat frequency response, the abridging of the impulse response provides a frequency response comparable with those obtained by other design methods
