Class C tuned amplifier is a large signal tuned amplifier that amplifies high power signals of the radio frequency range. The amplifier is said to be Class C if the output cycle obtained is less than half a cycle of the full input cycle. This means the transistor remains active for less than half a cycle so that only that much part of the input waveform is reproduced at the output with amplification. For the remaining part, the transistor remains inactive.

Which amplifier has more efficiency than class b amplifier?
Class C amplifier.. A class D amplifier is more efficient than class B, and is more efficient than class C as well.
What are two characteristics of class C Amplifiers?
A Class C amplifier typically uses less than fifty percent of the input signal in other amplifiers. It also has two modes of operation, which are tuned and untuned. The tuned circuit emits at a certain fixed frequency, while the untuned can vary.
What is high frequency tuned amplifier?
High frequency amplifier is a device which is tuned by high frequency. Tuned means the overlapping of generated frequency with that amplifier.
RF amplifier of an AM receiver is normally biased in class a class b class c?
class C because Class C also provides better signal,rejects unwanted signal.class c
How does the circuit of a collector modulation work?
The output stage of the transmitter is a high power frequency class C amplifier. Class C amplifiers conduct for only a portion of the positive half cycle of their input signal. The collector current pulses cause the tuned circuit to oscillate or ring at the desired output frequency. The tuned circuit, therefore, reproduces the negative portion of the carrier signal. The modulator is a linear power amplifier that takes the low level modulating signal and amplifies it to a high power level. The modulating output signal is coupled through modulation transformer T1 to the class C amplifier. The secondary winding of the modulation transformer is connected in series with the collector supply voltage Vcc of the class C amplifier.

What is the operation of class c tuned amplifier?
that is where the end stage does not consume current when there is no signal to amplify. Opposite of a class A where the current is constant with any signal level (except saturation...)

Class c amplifier advantage?
Efficiency of class C amplifier is approximately 100%.
What is meant by double tuned amplifier?
An amplifier with tuned filters on both input and output.
What amplification is done by class c amplifier?
a class c amplifier conducts only for a small fraction of the period ( cycle ) of the input signal. hence its use is normally limited to circuits called oscillators where the high efficiency & power gain inherent of class C is utilised together with tuned circuits. As a matter of information, high fidelity amplifiers used for professional audio etc. use class A amplifier, where the amplifier works continoulsy over the full period of the input signal. Then there is class B type where the amplifier works for about 50% of the input signal period. This type of amplifier is used especially in High frequency circuits where the use of a Tuned circuit enables a full cycle to be generated even though the amplifier is working as class B A variation of clss B used especially in audio systems is with Two class B circuits each operating synchronously over a particular half of the signal, the two halves being combined to generate a whole signal cycle. Then there are inbetween variations called class AB etc. Modern digital technology has introduced Class D type amplifiers which are a different lot altogether.
