4 The IN963 Zener diode in the simple voltage regulator circuit shown in Figure P9.53 has the specifications r, = 11.5 2 At the knee of curve, i4 = 0.25 mA V, = 12 V Prated = 400 mW F4 = 700 2 Determine the maximum rated current the diode can handle without exceeding its power limitation. T's

You are sampling a signal, with a sampling frequency of fs = 2000Hz. There are three frequency components of the signal, f₁ = 400Hz, f2 = 1200Hz, and f3 = 2100Hz. What are the frequencies that you will see? f1a f2a f3a Question 14 Question 15 Question 16 Hz Hz Hz If each of the original frequencies has an amplitude of 1.0 V, and you pass the signal through a passive low-pass filter with a cutoff frequency of 1200 Hz, what are the measured amplitudes of the signals. As a reminder, the Magnitude ratio of a low-pass filter is M(f) = √√₁+(+)² Ala Question 17 V A2a Question 18 V A3a Question 19 V
