Question

Answer the following with illustration and solutions.

1.) A certain cascaded amplifier arrangement has the following voltage gains: Av₁ = 22, Av₂ = 0.5, Av₃= 0.11 and Av₄ = 50. What is the overall voltage gain? Express each gain in decides (dB) and determine the total voltage gain in dB.

These is the example that might help...

Example:
A certain cascaded amplifier arrangement has the following voltage gains:
Av1 = 10, Av2 = 15, and Av3 = 20. What is the overall voltage gain?
Express each gain in decibels (dB) and determine the total voltage gain in dB.
Av2
Av3
av2 = 20log(Ap2)
av2 = 20log(15)
av2 = 23.52 dB
Step 2: Determine total gain in dB.
a'p(aR) = 20dB + 23.52dB + 26.02dB = 69.54 dB
Step 1: Determine each
gain in dB.
Apı = 20log(A,1)
avı = 20log(10)
avı = 20 dB
Alternately,
av3 = 20log(A,3)
Av3 = 20log(20)
ap3 = 26.02 dB
A', = Ap1Av2Av2 = 10(15)(20) = 3000
A', = 20 log(3000) = 69.54
