A scalable implementation scheme for multirate finite impulse response (FIR) filters is presented in this paper. The implementation scheme can reduce the time and area cost of a multirate FIR filter simultaneously. According to the throughput requirement, the proposed scheme achieves a minimum-area design with specified speed. Furthermore, by employing the scalable implementation scheme, we also propose an efficient design technique for subband filter banks
