Question:medium

The incorrect statement with respect to Bode Plots is

Show Hint

For stability using Bode plots: \[ GM>0\;dB \] and \[ PM>0^\circ \] indicate a stable system. Negative gain margin or negative phase margin generally indicates instability.

Updated On: Jun 25, 2026

Gain margin and phase margin both are positive then system is stable
Gain margin is measured above the \(0\,dB\) axis, then system is unstable
If the phase margin is measured below the \(-180^\circ\) axis, the system is stable
Absolute and relative stability of only minimum-phase system can be determined

Show Solution

The Correct Option is C
