Question 2

Consider the circuit shown in figure (a), the signal applied as input to the circuit is Vin [shown in figure (b)]

The voltage across diode VD is given as (Assuming diode to be ideal)

Question 3

In the figure shown below, all the diodes are ideal.

The value of current I is ________mA.

Question 4

A two sided limiting circuit has to be designed using two diode and two independent power supply which will supply power to a 1 kΩ load resistor with output voltage limiting levels of ± 3 V. Assuming the voltage gain of the circuit to be 0.95 V/V and the cut in voltages of diode to be 0.7. Then which of the following options represent that circuit?

Question 5

Which of the following is true? D1& D2 are ideal
