If in ajunction diode, a square input signal of 10 V is applied as shown

Then, the output signal across  will be                                            [AIEEE 2007]

A)

B)

C)

D)

Correct Answer: D

Solution :

[d] Forthe diode is reverse biased and hence, offer infinite resistance, so circuit would be like as shown in Fig. (2) given below and .

Forthe diode is forward biased and circuit would be as shown in Fig. (3) given below and

Hence, the option [d] is correct.
