registration number is 169

Sr. # Attribute 1. Task Description Take an audio signal composed of various (different) frequencies (e.g music signal) and process it as follow 1. Find the frequencies in the selected audio and display it. 2. Design "*" number of octave band pass II Butterworth filters 3. Pass the signal through these filters using either Direct Form I or Direct Form II of chapter 6. (Write your own function here) 4. Reconstruct the audio from the filtered output and listen to the original and filtered version and record your comments. *A" means your registration Number Mod 5 +3, for example if your registration number is 24, then A=4=3=7 Octave Bands Concept Discrete Fourier Transform, Filter design, Filter Implementation 2. Breadth Depth 4. Tools Matlab (1) 5. Investigation (ii) () What are octave bands and why they are important in audio signal processing How to design the IIR filers using Matlab Implementation of the filter for real time signal processing using own functions
