Two amplifiers are connected one after the other in series (cascaded). The first amplifier has a voltage gain of 10 and the second has a voltage gain of 20 . If the input signal is 0.01 V , calcualte the output AC signal .
Text Solution
Verified by Experts
Total voltage gain `A_(V)=(DeltaV_(0))/(DeltaV_(i))=A_(V_(1))xxA_(V_(2)) or DeltaV_(0)=DeltaV_(i)xxA_(V_(1))xxA_(V_(2)) =0.01xx10xx20=2V`
