  3. Bode plot - Wikipedia

    en.wikipedia.org/wiki/Bode_plot

    It is usually a combination of a Bode magnitude plot, expressing the magnitude (usually in decibels) of the frequency response, and a Bode phase plot, expressing the phase shift. As originally conceived by Hendrik Wade Bode in the 1930s, the plot is an asymptotic approximation of the frequency response, using straight line segments .

  4. Phase margin - Wikipedia

    en.wikipedia.org/wiki/Phase_margin

    Bode plot illustrating phase margin. In electronic amplifiers, the phase margin (PM) is the difference between the phase lag φ (< 0) and -180°, for an amplifier's output signal (relative to its input) at zero dB gain - i.e. unity gain, or that the output signal has the same amplitude as the input.

    Figure 5: Bode gain plot to find phase margin; scales are logarithmic, so labeled separations are multiplicative factors. For example, f 0 dB = βA 0 × f 1. Next, the choice of pole ratio τ 1 /τ 2 is related to the phase margin of the feedback amplifier. [9] The procedure outlined in the Bode plot article is followed. Figure 5 is the Bode ...

  6. Negative-feedback amplifier - Wikipedia

    en.wikipedia.org/wiki/Negative-feedback_amplifier

    The stability characteristics of the gain feedback product β A OL are often displayed and investigated on a Nyquist plot (a polar plot of the gain/phase shift as a parametric function of frequency). A simpler, but less general technique, uses Bode plots. The combination L = −β A OL appears commonly in feedback analysis and is called the ...

    en.wikipedia.org/wiki/Hendrik_Wade_Bode

    Hendrik Wade Bode (/ ˈ b oʊ d i / BOH-dee, Dutch:; [1] December 24, 1905 – June 21, 1982) [1] was an American engineer, researcher, inventor, author and scientist, of Dutch ancestry. As a pioneer of modern control theory and electronic telecommunications he revolutionized both the content and methodology of his chosen fields of research.

    English: The Bode plot of a Butterworth filter with logarithmic axes and various labels. Cutoff frequency is normalized to 1 rad/s. Gain is normalized to 0 dB in the passband. Phase is in degrees because that's typical. The code is kind of kludgy, but makes a good output.
