ECE 408 COMPUTER ASSIGNMENT #4 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) 1. Read a short wav file into Simulink and pass it through a digital elliptic lowpass filter with passband cutoff frequency 500Hz and stopband cutoff frequency of 600 Hz. Let α max = 2dB. α min = 25dB. 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. (c) Plot the spectrums (fft magnitude) before and after the filter. (d) Plot the impulse response, magnitude response, phase response, pole-zero diagram of

Repeat Problem #1 using a digital elliptic highpass filter with passband cutoff frequency 800Hz and stopband cutoff frequency of 700 Hz. 4. Repeat Problem #1 using a digital elliptic bandpass filter with lower passband cutoff frequency 1000Hz, upper passband cutoff frequency of 1500 Hz, lower stopband cutoff frequency 800Hz, upper stopband cutoff frequency 1700 Hz. 5. Repeat Problem #1 using a digital elliptic bandstop filter with lower passband cutoff frequency 800Hz, upper passband cutoff frequency of 1700 Hz, lower stopband cutoff frequency 1000Hz, upper stopband cutoff frequency 1500 Hz. 1...
