Interpretation Introduction

(b)

Interpretation:

The steady-state gain for the transfer function determined in part (a) is to be calculated.

Concept introduction:

In any steady state, the ratio of the amplitude of input signal to the amplitude of the amplifier output is known as steady-state gain. This gain will be same for the entire input range if the amplifier output is linear. For a transfer function, steady-state gain occurs as times tends to infinity which means that in s-domain, this infinite time is represented by s→0.

Interpretation Introduction

(c)

Interpretation:

It is to be determined if the steady-state gain calculated in part (b) can be unity based on the physical arguments only.
