Abstract -
This paper presents design and simulation of FIR filter for fixed point. Three different input precision bits are used for design simulation namely 8 bit, 16 bit and 32 bit. The design has been analyzed and compared in terms of accuracy and less stop band attenuation. The hardware requirement is also computed in terms of multipliers and adders. It can be observed from result that using more no of bits gives more accurate output signal. Multiplier and adders requirement will remain same if order is fixed f or all 8, 16 and 32 bit input signal.
