4. (8 points) Consider the circuit shown here with

Vin(t) = (1 V)sin(27 60Hz t), VDc = 3 V, C = 1 µF, and using

a constant-voltage model with Von = 0.7 V for D1. What are

the following values? (a) the minimum output voltage, (b)

the maximum output voltage, (c) the length of time that D1

is on each cycle after the circuit has been operating a long

time, and (d) the absolute value of the voltage across the

capacitor. (c) What type of wave-shaping circuit is this?
