The most common application of tank circuits is tuning radio transmitters and receivers. 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.
The change from a series arrangement to a parallel arrangement results in the circuit having a peak in impedance at resonance rather than a minimum, so the circuit is an anti-resonator. The graph opposite shows that there is a minimum in the frequency response of the current at the resonance frequency ω 0 = 1 / L C {\displaystyle ~\omega _{0 ...
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 ...
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.
Short lengths of Lecher line are often used as high Q resonant circuits, termed resonant stubs. For example, a quarter wavelength (λ/4) shorted Lecher line acts like a parallel resonant circuit, appearing as a high impedance at its resonant frequency and low impedance at other frequencies.
A resonant converter is a type of electric power converter that contains a network of inductors and capacitors called a resonant tank, tuned to resonate at a specific frequency. They find applications in electronics, in integrated circuits. [1] There are multiple types of resonant converter: Series resonant converter [2] Parallel resonant converter
Hartley oscillator using a common-drain n-channel JFET instead of a tube.. The Hartley oscillator is distinguished by a tank circuit consisting of two series-connected coils (or, often, a tapped coil) in parallel with a capacitor, with an amplifier between the relatively high impedance across the entire LC tank and the relatively low voltage/high current point between the coils.
A common form is the resonant stub, a length of transmission line terminated in either a short circuit or open circuit, connected in series or parallel with a main transmission line. Planar transmission-line resonators are commonly employed for coplanar , stripline , and microstrip transmission lines.
