ECE 408 COMPUTER ASSIGNMENT #6 SIMULINK EXPERIMENTS Useful blocks: Signal Processing Blockset Platform Specific I/O Windows (WIN32) From Wave Device From Wave File To Wave Device To Wave File Signal Processing Blockset Filtering Filter Designs Digital Filter Design (FDA Tool) Signal Processing Blockset Filtering Filter Designs Digital Filter Design Digital Filter (D F FIR) 1. Read a short wav file into Simulink and pass it through a 31-tap (order 30) FIR lowpass filter with cutoff frequency 500Hz using Hamming window. Create an output file in wav format. (a) Play the sound before and after the filter. (b) Plot the waveforms in the time domain before and after the filter.
