What does a Bode plot tell you?
Bode plots show the frequency response, that is, the changes in magnitude and phase as a function of frequency. This is done on two semi-log scale plots. The top plot is typically magnitude or “gain” in dB. The bottom plot is phase, most commonly in degrees.
Is Bode plot easy?
Bode plots are semilog plots of the magnitude (in decibels) and phase (in degrees) of a transfer function versus frequency. Bode plots contain the same information as the nonlogarithmic plots discussed in the previous section, but they are much easier to construct, as we shall see shortly.
