About this document

FIR Filter Design and Implementation Lab by Deepak Devaprasad is a document available to read on EtoBox.

This document describes designing and implementing a finite impulse response (FIR) filter. It discusses: 1) Designing an FIR filter in MATLAB to given specifications using fir2() and quantizing the coefficients using sfi(). 2) The JNI signature needed for a function that accepts a WaveFrame and returns a long. 3) Implementing the filter in C using 16-bit fixed-point arithmetic, and avoiding overflow by scaling the input signal.
