Q1 Figure Q1(a) is a full wave bridge circuit with a capacitor filter and the output waveform produced by the circuit is shown in Figure Q1(b). Assume all the diodes in the circuit have a forward voltage of 0.7 V. (a) (b) Sketch the waveform in A, B, C and D as shown in Figure Q1(a). Design the circuit by finding the value for the capacitor, C and the line voltage Vpri(rms) to the circuit to produce the output as shown in Figure Q1(b).

5) The figure below illustrates a simple voltage threshold detection circuit. To understand how it operates, we will analyze its behavior based on the simple constant voltage drop model for both diodes. Assume the Zener diode (Z1) only conducts when its breakdown voltage of 10V is reached. Di is a red light emitting diode (LED). Assume it conducts after its forward bias voltage of 1.8V is reached. Vin is unknown. Assume Zj acts as a perfect Zener diode (without series resistance). What voltage does Vin have to reach before there is a current through R¡? What voltage must Vin reach before current flows through R2? Write an equation for the current through Zi in terms of Vin, Rị and R2 that is valid when Vin is high enough for both diodes to be conducting. a. b. c. R2 Vino R1 LED
