tuned circuit |
Also found in: Wikipedia | 0.03 sec. |
tuned circuitElectrically conducting pathway containing both inductance and capacitance elements. When these elements are connected in series, the circuit presents low electrical impedance to alternating current of the same frequency as the resonance frequency of the circuit and high impedance to current of other frequencies. The circuit's resonance frequency is determined by the values of inductance and capacitance. When the circuit elements are connected in parallel, the impedance is high at the resonance frequency and low at other frequencies. With their ability to pass only certain frequencies, tuned circuits are important in, for example, radio and television receivers. tuned circuit [¦tünd ′sər·kət] (electronics) A circuit whose components can be adjusted to make the circuit responsive to a particular frequency in a tuning range. Also known as tuning circuit. How to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit webmaster's page for free fun content. |

| Tinier than their parent fractal antennae, fractal resonators are tuned circuits that radiate--but intentionally are made small so as to not radiate as well as other antennae. |
