Abstract

FIR filters that provide linear phases are frequently used in digital signal processing, voice and data transmission. Polyphase FIR filters are applied in many practical applications of DSPs that require the sampling rate of a signal to be changed. This paper describes the design and implementation of a high-speed programmable polyphase FIR filter. The FIR is designed to run automatically under all conditions according to the programmable configuration word including symmetry/asymmetry, odd/even taps, and 32 taps up to 256 taps. The maximum sampling frequency is obtained as 100MHz.
