The impulse response can be either finite or infinite. The methods for designing and implementing these two filter classes differ considerably. Finite Impulse Response (FIR) filters are digital filters whose response to unit impulse (unit sample function) is finite in duration. This paper presents the design of low power FIR filter and area efficient parallel linear phase FIR digital filter. Low power FIR filter uses the methods to reduce power consumption of a digital FIR filter and it is designed by using low power serial multiplier, serial adder, combinational Booth multiplier and D flip-flops which results in reduced glitch and power consumption.
