Certain investigations on design and implementation of digital fir filter using low power and high speed multipliers

Abstract

Processing where its impulse response duration is finite and it resolves to zero in finite time Since FIR filter provides a finite output for finite input it is always stable and this property is more useful in various DSP applications FIR filter can have a huge number of coefficients for a preferred frequency response with tight constraints on the transition band pass band and stop band The phase of the FIR filter is a linear function of the frequency because it has the linear phase property Here the signals of all frequencies are delayed by the same amount of time thereby eliminating the possibility of phase distortion This property implies that FIR can be used in audio applications The finite IO of FIR filter a stable property which is also very much useful in DSP The chief objective of this study is to design an efficient FIR filter for optimizing the power area delay and speed suitable for various DSP applications Due the efficiencies and advantages of the FIR filter this research work is motivated to design and implement a direct form of FIR filter using effective multipliers and adder circuits for optimizing the power area delay and speed in DSP Most of the existing research works were focused on utilizing FIR filter as an important component in various communications DSP and in portable applications newline
