1.Consider the circuit shown in Figure 8.33. The input voltage is sinusoidal(AC),with a peak amplitude of 3 V. The resistor has a value of 1 kohm. When conducting, the two diodes have a forward drop of 0.7 V. Make a sketch of the output voltage. Carefully label your axes.
2.Design a clipping circuit that limits the voltage of an input signal to within the range −5 V to +5 V.
3.The circuit of Figure8.37 is a Cockroft-Walton multiplier. The input signal is a square wave with a high voltage Vp and a low voltage of zero volts.
(a) What is the output voltage? (Neglect diode drops.)
(b) If Vp = 5 V, find the output voltage, including diode drops of 0.6 V.
