Generally, the phase shift φ is a function of frequency. The magnitude axis of the Bode plot is usually expressed as decibels, that is, 20 times the common logarithm (20 log 10) of the amplitude of the gain.Ī Bode phase plot is a graph of phase versus frequency, also plotted on a log-frequency axis, to evaluate how much a signal will be phase-shifted. A Bode plot, named after Hendrik Wade Bode, is a combination of a Bode magnitude plot and Bode phase plot, that shows the transfer function or frequency response of a linear, time-invariant system using a log-frequency axis (frequency in powers of 10).Ī Bode magnitude plot (also referred to as the Bode gain plot) is a graph of log magnitude versus frequency.
