Abstract
This paper proposes a design of a new finite impulse response (FIR) digital filter structure which gives 6-tunable frequency responses as 2 low-pass filters (LPF), 2 high-pass filters (HPF), 1 band-pass filter (BPF) and 1 band-stop filter (BSF) at the same time. The design procedure is initiated from 2 LPFs design. However in order to obtain a tunable filter, the unit delay is replaced by first-order single-multiplier structure for all-pass filter. Therefore, this new structure can be achieved and called tunable multiple outputs FIR filter. Finally, the amplitude responses that obtained from proposed structure can show the tunable capability using tuning parameter.
