Question
Physics Question on Semiconductor electronics: materials, devices and simple circuits
For a transistor amplifier, the voltage gain
A
remains constant for all frequencies.
B
is high at high and low frequencies and constant in the middle frequency range
C
is low at high and low frequencies and constant at mid frequencies.
D
None of the above.
Answer
is low at high and low frequencies and constant at mid frequencies.
Explanation
Solution
The correct statement is (C): is low at high and low frequencies and constant at mid frequencies.
The voltage gain of a transistor amplifier is constant at mid frequency range only. It is low at high and low frequencies.
