  2. Amplitude - Wikipedia

    en.wikipedia.org/wiki/Amplitude

    Peak-to-peak amplitude (abbreviated p–p or PtP or PtoP) is the change between peak (highest amplitude value) and trough (lowest amplitude value, which can be negative). With appropriate circuitry, peak-to-peak amplitudes of electric oscillations can be measured by meters or by viewing the waveform on an oscilloscope .

  3. Crest and trough - Wikipedia

    en.wikipedia.org/wiki/Crest_and_trough

    Crest and trough in a wave. A Crest point on a wave is the highest point of the wave. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point of the wave.

  4. Resonance - Wikipedia

    en.wikipedia.org/wiki/Resonance

    Increase of amplitude as damping decreases and frequency approaches resonant frequency of a driven damped simple harmonic oscillator. [1] [2]Resonance is a phenomenon that occurs when an object or system is subjected to an external force or vibration that matches its natural frequency.

  5. Amplitude (disambiguation) - Wikipedia

    en.wikipedia.org/wiki/Amplitude_(disambiguation)

    Amplitude Studios, a video game developer; Amplitude (2003 video game), a 2003 music video game for the PlayStation 2 Amplitude (2016 video game), a 2016 reboot of the 2003 video game for the PlayStation 3 and PlayStation 4

  6. Wave equation - Wikipedia

    en.wikipedia.org/wiki/Wave_equation

    A so-called eigenmode is a solution that oscillates in time with a well-defined constant angular frequency ω, so that the temporal part of the wave function takes the form e −iωt = cos(ωt) − i sin(ωt), and the amplitude is a function f(x) of the spatial variable x, giving a separation of variables for the wave function: (,) = ().

  7. Spectrogram - Wikipedia

    en.wikipedia.org/wiki/Spectrogram

    The frequency and amplitude axes can be either linear or logarithmic, depending on what the graph is being used for. Audio would usually be represented with a logarithmic amplitude axis (probably in decibels, or dB), and frequency would be linear to emphasize harmonic relationships, or logarithmic to emphasize musical, tonal relationships.

  9. Waveform - Wikipedia

    en.wikipedia.org/wiki/Waveform

    In these cases, the waveform is an attribute that is independent of the frequency, amplitude, or phase shift of the signal. The waveform of an electrical signal can be visualized in an oscilloscope or any other device that can capture and plot its value at various times, with suitable scales in the time and value axes.
