For the circuit in the figure below, in which the diode has a value Vd = 0.7 V:   Calculate the two values of Vout. Calculate the value of Vin that will cause Vout to change between the two levels found in part a). Sketch the signal Vout. Include values for time and voltages

Sketch the output waveform and indicate the expected voltage levels for each of these diode circuits below. Use the diode models as indicated.

For the circuit in the figure, let V input = 8V, Ri = 12ohms, RL = 10ohms, and VZ = 3.3V. Determine the voltages and currents of the resistors and the current of the zener diode.

Vi (t) = 10.sinwt Does not pass positive alternans when Volt input voltage is applied, only Design and explain two different circuits that pass negative alternans. Draw the input and output voltages. What are the types of these circuits? (Note: You can use the ideal diode approach)
