Multiplicative finite impulse response filters: implementations and applications using field programmable gate arrays

This study describes how modern field programmable gate array (FPGA) technology can be used to build practical and efficient multiplicative finite impulse response (MFIR) filters with low-pass, high-pass, band-pass and band-stop characteristics. This study explains how MFIR structures can be built with or without linear phase characteristics and implemented efficiently on modern FPGA architectures using fixed-point arithmetic without incurring stability problems or limit cycles which commonly occur when using equivalent infinite impulse response structures. These properties have a particular importance for applications such as tunable resonators, narrow band rejectors and linear phase filters which have demanding, narrow transition band requirements. The results presented in this study indicate that MFIR filters are, for some applications, a viable alternative to existing filter structures when implemented on an FPGA.
