  2. Bode plot - Wikipedia

    en.wikipedia.org/wiki/Bode_plot

    Figures 2-5 further illustrate construction of Bode plots. This example with both a pole and a zero shows how to use superposition. To begin, the components are presented separately. Figure 2 shows the Bode magnitude plot for a zero and a low-pass pole, and compares the two with the Bode straight line plots.

  3. Cutoff frequency - Wikipedia

    en.wikipedia.org/wiki/Cutoff_frequency

    Magnitude transfer function of a bandpass filter with lower 3 dB cutoff frequency f 1 and upper 3 dB cutoff frequency f 2 Bode plot (a logarithmic frequency response plot) of any first-order low-pass filter with a normalized cutoff frequency at =1 and a unity gain (0 dB) passband.

  4. Step response - Wikipedia

    en.wikipedia.org/wiki/Step_response

    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 gain plot for the two-pole amplifier in the range of frequencies up to the second pole position.

  5. 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.

  6. Smith chart - Wikipedia

    en.wikipedia.org/wiki/Smith_chart

    To plot this, one may use the circumferential (reflection coefficient) angle scale to find the graduation and a ruler to draw a line passing through this and the centre of the Smith chart. The length of the line would then be scaled to P 1 assuming the Smith chart radius to be unity.

  8. Plot (graphics) - Wikipedia

    en.wikipedia.org/wiki/Plot_(graphics)

    Ridgeline plot: Several line plots, vertically stacked and slightly overlapping. Q–Q plot : In statistics, a Q–Q plot (Q stands for quantile) is a graphical method for diagnosing differences between the probability distribution of a statistical population from which a random sample has been taken and a

  9. Lissajous curve - Wikipedia

    en.wikipedia.org/wiki/Lissajous_curve

    Top: Output signal as a function of time. Middle: Input signal as a function of time. Bottom: Resulting Lissajous curve when output is plotted as a function of the input. In this particular example, because the output is 90 degrees out of phase from the input, the Lissajous curve is a circle, and is rotating counterclockwise.
