Q.
Two amplifiers are connected one after the other in series. The first amplifier has a voltage gain of $10$ and second has voltage gain of $20$ . If the input signal is $0.01\, V$ then output signal is :-
Solution:
Total $A _{ v }= A _{ v _{1}} \times A _{ v _{2}}$
$=10 \times 20=200$
So, $\frac{\text { Output Signal }}{\text { Input Signal }}= A _{ v }$
$\Rightarrow \frac{\text { Output Signal }}{0.01}=200$
$\Rightarrow $ Output Signal $=2\, V$
