If in a\[x\ne 0\]junction diode, a square input signal of 10 V is applied as shown Then, the output signal across \[{{R}_{L}}\] will be     AIEEE  Solved  Paper-2007

A)  

B)         

C)              

D)         

Correct Answer: D

Solution :

For\[2a/\sqrt{3}\]the diode is reverse biased and hence, offer infinite resistance, so circuit would be like as shown in Fig. (2) given below and \[{{V}_{o}}=0\]. For\[a/\sqrt{3}\]the diode is forward biased and circuit would be as shown in Fig. (3) given below and\[a\sqrt{3}\] Hence, the option (d) is correct.
