TUNED CIRCUIT Meaning and
Definition
-
A tuned circuit is an electronic circuit that is specifically designed to resonate at a particular frequency or a narrow range of frequencies. It consists of inductors (coils) and capacitors arranged in a specific configuration to create a resonance effect. The primary function of a tuned circuit is to selectively amplify or attenuate signals at its resonant frequency, while rejecting or reducing signals at other frequencies.
The resonant frequency of a tuned circuit depends on its inductance and capacitance values. When a signal of the resonant frequency is inputted, the energy is stored in the inductors and capacitors, causing the circuit to oscillate. This resonance effect enhances the electrical energy at the desired frequency.
Tuned circuits find applications in various electronic devices including radios, televisions, and communication systems. In radios, for instance, they are utilized to select and amplify specific radio frequencies. By adjusting the values of inductors or capacitors, the resonant frequency of the circuit can be changed, allowing for the tuning of different radio stations.
Tuned circuits are considered essential components in many electronic systems as they improve selectivity and signal quality. They are commonly used in combination with other electronic components such as amplifiers, filters, and transmitters to optimize circuit performance and ensure efficient signal transfer.
Etymology of TUNED CIRCUIT
The word "tuned circuit" derives from the combination of two separate terms: "tuned" and "circuit".
- "Tuned" refers to the act of adjusting or making something in harmony or to a specific frequency. In the context of electronics, it signifies aligning an electrical device or component, such as a circuit or an antenna, to a desired frequency.
- "Circuit" represents a complete path through which an electric current can flow. In electronics, it refers to a closed loop or a network of interconnected electronic components that perform various functions.
When these terms are combined, "tuned circuit" refers to an electronic circuit or network that is designed and adjusted to resonate at a particular frequency or range of frequencies. This type of circuit is often used in systems like radios, televisions, and communication devices to select and amplify specific signals while rejecting others.
