  2. 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 .

  3. Iso-damping - Wikipedia

    en.wikipedia.org/wiki/Iso-damping

    Bode's ideal control loop frequency response has the fractional integrator shape and provides the iso-damping property around the gain crossover frequency. This is due to the fact that the phase margin and the maximum overshoot are defined by one parameter only (the fractional power of s {\displaystyle s} ), and are independent of open-loop gain.

  4. Frequency response - Wikipedia

    en.wikipedia.org/wiki/Frequency_response

    Magnitude response of a low pass filter with 6 dB per octave or 20 dB per decade roll-off. Measuring the frequency response typically involves exciting the system with an input signal and measuring the resulting output signal, calculating the frequency spectra of the two signals (for example, using the fast Fourier transform for discrete signals), and comparing the spectra to isolate the ...

    en.wikipedia.org/wiki/List_of_open-source...

    SageMath is designed partially as a free alternative to the general-purpose mathematics products Maple and MATLAB. It can be downloaded or used through a web site. SageMath comprises a variety of other free packages, with a common interface and language. SageMath is developed in Python.

  6. Nichols plot - Wikipedia

    en.wikipedia.org/wiki/Nichols_plot

    The Nichols plot is a plot used in signal processing and control design, named after American engineer Nathaniel B. Nichols. [ 1 ] [ 2 ] [ 3 ] It plots the phase response versus the response magnitude of a transfer function for any given frequency, and as such is useful in characterizing a system's frequency response .

  8. Transimpedance amplifier - Wikipedia

    en.wikipedia.org/wiki/Transimpedance_amplifier

    The Bode plot of a transimpedance amplifier that has a compensation capacitor in the feedback path is shown in Fig. 5, where the compensated feedback factor plotted as a reciprocal, 1/β, starts to roll off before f i, reducing the slope at the intercept. The loop gain is still unity, but the total phase shift is not a full 360°.

  9. HuffPost looked at how killers got their guns for the 10 deadliest mass shootings over the past 10 years. To come up with the list, we used Mother Jones’ database, which defines mass shootings as “indiscriminate rampages in public places” that kill three or more people.
