Abstract: The paper gives a design for digital bandpass filters. The de?signed filter can automotlcally accomplish the desired task according to tar?gets assigned. It can provide not only the required magnitude of frequency response, phase response,transfer function and output response,but also the filterˊs parameters in cascade or paralled form. The paper discusses also the digital filterˊs applications in the simulation of proximity fuzes,giving sa?tisfactory results through simulation analyses.

Key words: digital simulation, Doppler signal, frequency change beforehand, bi-linear exchange
