Audio Filtering By: Rudrapratap Jadhav ECE 3551 Microcomputer System

Introduction The audio was manipulated with the help of four filters: o Two High pass o Two Low pass The main goal of this project was to separate the above frequencies from the original audio

Implementation Pressing PF8 will initiate the first low pass filter and also activate LED 1 Pressing PF9 will initiate the first high pass filter and also activate LED 2 Pressing PF10 will initiate the second low pass filter and activate LED 3 Pressing PF 11 will initiate the second high pass filter and activate LED 4

Filter Design The filters were designed using MATLAB software Chebychev type 2 was the design type utilized for all the filters. The coefficient values were extracted and placed in the code

Results and Conclusion I was able to separate the low and the high frequencies with the two types of filters used in this project
