A low complexity and high modularity design for continuously variable bandwidth digital filters

Digital filters with variable bandwidth can be used for a variety of applications. Arbitrary change in the digital Finite Impulse Response (FIR) filter acquired using sampling rate converters (SRCs). In this paper, SRC is proposed which generated from Pascal structure, fractional delay having low hardware complexity and high modularity. A low-pass single sandwiched between two SRCs contribute multiple bandwidths such way that each an arbitrary variation original bandwidth. two-stage frequency response masking (FRM) approach efficient design filter. modularity novel continuously varying FIR paper SRC. The structure to control both pass band ripple as well stop attenuation design. Different communication standards software-defined radio (SDR) channelizer realised
