Introduction
The frequency response is a representation of the system's response to sinusoidal inputs at varying frequencies. The output of a linear system to a sinusoidal input is a sinusoid of the same frequency but with a different magnitude and phase. The frequency response is defined as the magnitude and phase differences between the input and output sinusoids.
The frequency response comprises of two parts:
1. Gain Response
2.Phase Response
The frequency response of a system can be viewed two different ways: via the Bode plot or via the Nyquist diagram. …
