11) In a three stage cascade amplifier, if the gain of first stage is 50, of second stage is 10 and of third stage is 5, then what is the overall gain ?

27.689

55.378

65.0

2500

Answer is:

2500

Poor low frequency response

Higher cost

Needs a ripple free power supply

Insensitive to temperature changes

Answer is:

bias resistors

capacitive reactance

inductive reactance

transistor

Answer is:

low d.c. resistance and high impedance

low d.c. resistance and low impedance

high d.c. resistance and high impedance

high d.c. resistance and low impedance

Answer is:

its cost is high

it is bulky

it does not give a uniform frequency response over the entire a.f. range

all the above stated drawbacks

Answer is:
