  3. Bode plot - Wikipedia

    en.wikipedia.org/wiki/Bode_plot

    Figure 10: Amplitude diagram of a 10th-order electronic filter plotted using a Bode plotter. 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 ...

    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.

    This can be apportioned to two first order lattices in cascade, using the Type IV circuits from Bode’s chart [6]: 252 to give the circuit shown. Bode equalizer (lattice) Bode equalizer (bridged-T) This can be easily converted to a cascade of standard constant resistance bridged-T sections of the form described earlier, as shown on the right.

  6. 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 ...

  7. Constellation diagram - Wikipedia

    en.wikipedia.org/wiki/Constellation_diagram

    After passing through a communication channel, due to electronic noise or distortion added to the signal, the amplitude and phase received by the demodulator may differ from the correct value for the symbol. When plotted on a constellation diagram the point representing that received sample will be offset from the correct position for that symbol.
