Bode diagram

The frequency response characteristic of a system is represented by the

Bode diagram. The bode diagram is known in the honor of H.W.Bode and it

is convenient way for analysis of the frequency of a linear control system.

Amplitude ratio AR and the phase angle are the functions of the

frequency w.

The bode diagram consists of a pair of the following graphs.

1. The variation of the logarithm of the amplitude ratio with radian

frequency.

2. The variation of the phase angle with radian frequency.
