Mcm Based Digital Filter for Audio Applications

Abstract

In Digital signal processing, the concept of digital filter plays a major role. To design efficient filter the order should be small. A minimum order Finite Impulse Response (FIR) digital filter is designed for filtering noise from audio signal [5].

 In this paper we propose the computationally efficient, low memory, low area and low delay FIR filter design using multiplier less multiple constant multiplication technique and synthesized using Xilinx ISE 13.2. The extended architecture of Digital filter is capable of filtering 16 bit of input data signal by using delays, adders and MCM. This architecture shows reduction in memory, area utilization and delay. The depth of operation reduced to avoid glitches.
