For the following closed-loop transfer functions, sketch the bode plots (magnitude and phase), iden- tifying the zero gain, the slopes (in Decibels) and the high-frequency cutt-off rate. Then verify with Matlab (6) wn = 1, 〈 0.0.1, and 0.707. (8) Assuming the system of Problem 6 above, and an input of r(t) = 30sin(1000 t), use your bode plot to obtain the steady-state response

ffset sawtooth wave x(t). 1-7 A binary signal x(t) = 0 for t <0. For posi- tive time, x(t) toggles between one and zero as follows: one for 1 second, zero for 1 second, one for 1 second, zero for 2 seconds, one for 1 1-11 second, zero for 3 seconds, and so forth. That is, the "on" time is always one second but the “off” time successively increases by one sec- ond between each toggle. A portion of x(t)...
