What is Rejector circuit definition?
noun. Electronics. A circuit comprising a capacitor and an inductor connected in parallel, having values chosen such that the combination offers a very high impedance to signals of a particular frequency.
What is acceptor and Rejector circuit?
– Series resonance circuit is aka acceptor circuit as it accepts current at resonant frequency. – Impedance is minimum here. – Voltage is magnified in acceptor circuit. ● Acceptor circuit – – Parallel resonance circuit is aka rejector circuit as its current is minimum at resonant frequency.
What is application of acceptor circuit?
(1) As frequency selection circuit in radio and TV tuner circuits. (2) As a bandpass filter circuit. Note: Series LRC circuit also called tuned circuit have many applications in radio and communication engineering. The acceptor circuit provides the maximum response to currents at its resonant frequency.
Which circuit is called as acceptor circuit?
Series Circuit Current at Resonance As a series resonance circuit only functions on resonant frequency, this type of circuit is also known as an Acceptor Circuit because at resonance, the impedance of the circuit is at its minimum so easily accepts the current whose frequency is equal to its resonant frequency.
What is a Rejector?
1. to refuse to accept, acknowledge, use, believe, etc. 2. to throw out as useless or worthless; discard. 3.
Which circuit is Rejector circuit?
Parallel resonant circuit is used as filter circuit because such circuit rejects the currents corresponding to the parallel resonant frequencies and allow other frequencies to pass, hence called as filter circuit or rejector circuit.
Why the circuit is named as Rejector circuit?
As a parallel resonance circuit only functions on resonant frequency, this type of circuit is also known as an Rejecter Circuit because at resonance, the impedance of the circuit is at its maximum thereby suppressing or rejecting the current whose frequency is equal to its resonant frequency.
What is RLC Rejector circuit?
At frequencies other than resonance, the impedance is much less. So, the parallel tuned circuit rejects signals at or near its resonant frequency and allows signals of frequencies other than resonance to pass. This is why the parallel tuned circuit is called a rejector circuit.
Why parallel resonance is called Rejector circuit?
What is series resonant circuit?
Series resonance is a resonance condition that usually occurs in series circuits, where the current becomes a maximum for a particular voltage. In series resonance, the current is maximum at resonant frequency. The series resonance current curve increases to a maximum at resonance then decreases as resonance is passed.
What is resonance in LCR circuit?
Resonance is the phenomenon in the circuit when the output of that electric circuit is maximum at one particular frequency. In LCR series circuits, resonance occurs when the value of inductive and capacitive reactances have equal magnitude but have a phase difference of 180°. Thus, they cancel each other.
What is Q factor in physics?
In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is approximately defined as the ratio of the initial energy stored in the resonator to the energy lost in one radian of the cycle of oscillation.
What is the function of an acceptor circuit?
The acceptor circuit provides the maximum response to currents at its resonant frequency. As a series resonance circuit, the only function on resonant frequency and the impedance of the acceptor circuit is minimum but the voltage can be magnified.
Why is a series resonance circuit called an acceptor circuit?
A series resonance circuit is also known as an Acceptor Circuit because at resonance, the impedance of the circuit is at its minimum so easily accepts the current whose frequency is equal to its resonant frequency or we can say that it functions mainly at resonance. On the other hand, in a parallel resonance circuit like:
What does the term acceptor mean in physics?
Also called acceptor atom, acceptor impurity. Physics. an atom of impurity in a semiconducting crystal such that the atom can capture an electron, creating a hole in a filled electron shell and thereby changing the electric conductivity of the crystal.
Why is RLC circuit known as acceptor circuit?
Series RLC circuit is known as acceptor circuit because at resonance the impedance of the circuit is at its minimum to easily accepts the current where frequency is equal to its resonant frequency or we can say that it functions mainly at resonance.
