  2. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    This circuit does not have a resistor like the above, but all tuned circuits have some resistance, causing them to function as an 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 ...

  3. Electrical resonance - Wikipedia

    en.wikipedia.org/wiki/Electrical_resonance

    A tesla coil is a high-Q resonant circuit. Electrical resonance occurs in an electric circuit at a particular resonant frequency when the impedances or admittances of circuit elements cancel each other. In some circuits, this happens when the impedance between the input and output of the circuit is almost zero and the transfer function is close ...

  4. Resonance - Wikipedia

    en.wikipedia.org/wiki/Resonance

    An RLC circuit is used to illustrate connections between resonance and a system's transfer function, frequency response, poles, and zeroes. Building off the RLC circuit example, these connections for higher-order linear systems with multiple inputs and outputs are generalized.

  5. Q factor - Wikipedia

    en.wikipedia.org/wiki/Q_factor

    The definition of Q since its first use in 1914 has been generalized to apply to coils and condensers, resonant circuits, resonant devices, resonant transmission lines, cavity resonators, [5] and has expanded beyond the electronics field to apply to dynamical systems in general: mechanical and acoustic resonators, material Q and quantum systems such as spectral lines and particle resonances.

  6. Resonator - Wikipedia

    en.wikipedia.org/wiki/Resonator

    Such resonant circuits are also called RLC circuits after the circuit symbols for the components. A distributed-parameter resonator has capacitance, inductance, and resistance that cannot be isolated into separate lumped capacitors, inductors, or resistors. An example of this, much used in filtering, is the helical resonator.

  7. RL circuit - Wikipedia

    en.wikipedia.org/wiki/RL_circuit

    A resistor–inductor circuit (RL circuit), or RL filter or RL network, is an electric circuit composed of resistors and inductors driven by a voltage or current source. [1] A first-order RL circuit is composed of one resistor and one inductor, either in series driven by a voltage source or in parallel driven by a current source.

  8. Coupling coefficient of resonators - Wikipedia

    en.wikipedia.org/wiki/Coupling_coefficient_of...

    All diagonal elements in a tuned filter are equal to zero because a susceptance vanishes at the resonant frequency. Important merit of the matrix is the fact that it allows to directly compute the frequency response of the equivalent network having the inductively coupled resonant circuits,.

  9. LC circuit - Wikipedia

    en.wikipedia.org/wiki/LC_circuit

    For example, when tuning a radio to a particular station, the LC circuits are set at resonance for that particular carrier frequency. A series resonant circuit provides voltage magnification. A parallel resonant circuit provides current magnification. A parallel resonant circuit can be used as load impedance in output circuits of RF amplifiers.
