Using Fig. P12.40, at what frequency does the quadratic pole break (the 3dB frequency of the quadratic pole)? Given w1 = [t1] rad/s, w2 = 15rad/s, w3 = 44rad/s, and w4= 561rad/s.

Consider the CT sinusoid x(t) = sin 4t. What are the frequencies of its sampled sequences if the sampling period T are 0.3, 0.6, 0.9, and 1.2? Do they equal the frequency of sin 4r? Under what condition on 7 will the frequency of sin 4nT equal 4 rad/s?

The curve is described by V(t)=Vm*cos(w*t+theta) + Vshift. Given V1= 1 volts, V2=-V1, V3=0.2450 volts, and T=9.500 msec. Find Vm (volts), w (rad/sec), t3 (msec), theta (deg), and vshift (volts).
