Bode plot and nyquist plot difference
WebDec 16, 2024 · An example is shown below alongside the corresponding Bode plot, which shows impedance magnitude and phase. At the peak in the Nyquist plot, we have a corresponding dip in the phase of the Bode plot. These points are shown in the example graphs below. Nyquist plot and corresponding Bode plot examples for … WebOct 24, 2024 · The Nyquist plot is at -90 degrees when the phase lag is -90 degrees. This occurs over the frequency range during which the slope of the magnitude curve on the bode plot is truly -20dB/decade. The -20dB/ decade slope will start to become steeper than -20dB/decade from about a decade below that double pole.
