A Bode magnitude plot is a graph of log magnitude versus frequency, plotted with a log-frequency axis, to show the frequency response of a linear system.A Bode phase plot is a graph of phase versus frequency, also plotted on a log-frequency axis, usually used in conjunction with the magnitude plot, to evaluate how much a frequency will be phase-shifted.
