If the following input signal is sent through a PN-junction diode, then the output signal across RL will be

A)                                         

B)                                  

C)                                          

D)                                 

Correct Answer: C

Solution :

           When input voltage is ­? 10 V, the diode is reverse biased and no output is obtained. On the other hand, when input is +10V, the diode is forward biased and output is obtained which is +10V. Therefore the output is of the form as show in the following figure.
