I-V characteristics of four devices are shown in figure.
Identify devices that can be used for modulation
Text Solution
Verified by ExpertsThe correct answer is:
C
: Here
(i) Represent ideal modulation related to triode valve for linear plate modulation
(ii) Represent square law diode modulation
(iii) Represent constant current source
(iv) Represent part of it as square law modulation.
Thus, for modulation, (ii) and some regions of (iv) can be used
