Cutoff frequency bode plot

The Bode plotter is an electronic instrument resembling an oscilloscope, which produces a Bode diagram, or a graph, of a circuit's voltage gain or phase shift plotted against frequency in a feedback control system or a filter. An example of this is shown in Figure 10. It is extremely useful for analyzing and testing filters and the stability of feedback control systems, through the measurement of corner (cutoff) frequencies and gain and phase margins. WebJan 8, 2024 · The image below shows the Bode plot for a 1st-order low pass filter (top: magnitude, bottom: phase). The phase plot shows how the phase shift develops when the source frequency starts to enter the cutoff region. Here, when the phase shift in the Bode plot is 45 degrees, the magnitude curve passes through approximately -3 dB.
