Question:
In the figure shows the transfer characteristics of a base biased CE transistor. Which of the following statements are true?
(a) At Vi = 0.4V, transistor is in active state
(b) At Vi = 1V, it can be used as an amplifier
(c) At Vi = 0. .5V, it can be used as a switch turned off
(d) At Vi = 2.5V, it can be used as a switch turned on
Solution:
(b) At Vi = 1V, it can be used as an amplifier
(c) At Vi = 0. .5V, it can be used as a switch turned off
(d) At Vi = 2.5V, it can be used as a switch turned on
