Unformatted text preview: = c = 5 rad/s and check if the result reproduces the filters calculated in 1). 3) Implement all three filters in state-variable form in SIMULINK. Pass through each filter the sawtooth waveform (generated by the sawtooth function in the Signal Processing Toolbox) with the period T=1 sec. given by t, 0 t 1, and plot the resulting output waveforms (in the time domain, one underneath the other). 4) For each output waveform, calculate (analytically) the single-sided magnitudes of the two harmonics adjacent to the filter cut-off frequency - one to the left and the other to the right, and plot the single-sided magnitudes of these harmonics on the same graph as the function of the filter order. Indicate if the changes in the magnitudes of these harmonics as a function of filter order in the frequency domain are visible on the time domain graphs of the filter output waveforms. 5) Implement the first two filters in the state-variable scheme using inverting op amps....
