I-V characteristics of four devices are shown in figure.

Identify devices that can be used for modulation

A

(i) and (iii)

B

Only (iii)

C

(iii) and some regions of (iv)

D

All the devices can be used

Text Solution

Verified by Experts

The correct Answer is:
C
Here, (i) represents ideal modulation related to triode valve for linear plate modulation.
(ii) represents square law diode modulation.
(iii) represents constant current source.
(iv) represents part of it as square law modulation. Thus, for modulation (iii) and some regions of (iv) can be used.
