Chapter 18

Q. 18.5

In Fig. 18-22, R_1 = 1 \ kΩ, R_2 = 2 \ kΩ, R_3 = 3 \ kΩ, R_4 = 4 \ kΩ, R_5 = 5 \ kΩ, and R_f = 6 \ kΩ . What is the voltage gain of each channel?

Step-by-Step

Verified Solution

With the equations given in Fig. 18-22, the voltage gains are:

A_{V1}=\frac{-6 \ k\Omega }{ 1 \ kΩ }=-6

A_{V2}=\frac{-6 \ k\Omega }{ 2 \ kΩ }=-3

A_{V3}=\left(\frac{6 \ k\Omega }{ 1 \ kΩ\parallel 2 \ k\Omega }+1\right) \frac{4 \ k\Omega \parallel 5 \ k\Omega }{3 \ kΩ + 4 \ kΩ ∥ 5 \ kΩ}= 4.26

A_{V4}=\left(\frac{6 \ k\Omega }{ 1 \ kΩ\parallel 2 \ k\Omega }+1\right) \frac{3 \ k\Omega \parallel 5 \ k\Omega }{4 \ kΩ + 3 \ kΩ ∥ 5 \ kΩ}= 3.19
