摘要:In radar EW applications, the problem of simultaneous signal remains as a problem of DIFM receiver ,which is being solved using the digital receiver.. A low SNR signals can be processed only using the digital receiver which is not possible using the analog receiver. These digital receivers are well suited to perform as wide band Channelizer, tunedsuperheterodyne receiver, compressive receiver functions .In this paper we have analysed and studied the advantages of designing the digital receiver using monobit and multibit fft algorithms ,simulation results of algorithms are presented.
