  2. Fundamental frequency - Wikipedia

    en.wikipedia.org/wiki/Fundamental_frequency

    The fundamental frequency, often referred to simply as the fundamental (abbreviated as f 0), is defined as the lowest frequency of a periodic waveform. [1] In music, the fundamental is the musical pitch of a note that is perceived as the lowest partial present. In terms of a superposition of sinusoids, the fundamental frequency is the lowest ...

  3. Utility frequency - Wikipedia

    en.wikipedia.org/wiki/Utility_frequency

    The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user. In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it ...

  4. LC circuit - Wikipedia

    en.wikipedia.org/wiki/LC_circuit

    An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together. The circuit can act as an electrical resonator, an electrical analogue of a tuning fork, storing energy oscillating at the ...

  5. Harmonics (electrical power) - Wikipedia

    en.wikipedia.org/wiki/Harmonics_(electrical_power)

    Harmonics (electrical power) In an electric power system, a harmonic of a voltage or current waveform is a sinusoidal wave whose frequency is an integer multiple of the fundamental frequency. Harmonic frequencies are produced by the action of non-linear loads such as rectifiers, discharge lighting, or saturated electric machines.

  6. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC.

  7. Crystal oscillator frequencies - Wikipedia

    en.wikipedia.org/wiki/Crystal_oscillator_frequencies

    Allows binary division to 60 Hz (65536×60 Hz, 2 16 ×60 Hz), used e.g. in wattmeters, DC-AC converters and NTSC vertical sync generators 4.000 Common general low-power microcontroller frequency. Common as cheap ceramic resonators where frequency stability is of less concern than cost. 4.032 7200

  8. Frequency - Wikipedia

    en.wikipedia.org/wiki/Frequency

    Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. For example, if a heart beats at a frequency of 120 times per minute (2 hertz), the period—the interval between beats—is half a second ...

  9. Sampling (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Sampling_(signal_processing)

    In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave to a sequence of "samples". A sample is a value of the signal at a point in time and/or space; this definition differs from the term's usage in statistics, which refers to a set of such values.
