What is Class B push-pull amplifier?
When we get amplifier output current for 180 degrees of input. then it's called B class amplifier. In a push pull class B amplifier one of the two power transistors or other amplifying elements handles the positive half of the waveform and the other element handles the negative half of the waveform. In practice, push pull audio amplifiers are usually class AB; each power transistor handles slightly more than 180 degrees of input. This minimizes distortion (crossover distortion) when one of the two transistors ceases output and the other takes over.
What is class c tuned amplifier?
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.
What is wideband amplifier?
A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave. The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ). The "opposite" concept is the narrow-band or tuned amplifier. There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor. end-
Need of multistage amplifier?
The Gain provided by the multistage amplifier is greater than the gain of single stage amplifier. The gain of the two stage amplifier is the product of the gain of the individual stages.
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.
Why efficiency of class c amplifier is high?
It conducts for less than one half cycle of the input.
What is Class B push-pull amplifier?
When we get amplifier output current for 180 degrees of input. then it's called B class amplifier. In a push pull class B amplifier one of the two power transistors or other amplifying elements handles the positive half of the waveform and the other element handles the negative half of the waveform.

This minimizes distortion (crossover distortion) when one of the two transistors ceases output and the other takes over.
What is a class c amplifier?
A class A amplifier is an amplifier where the bias current in all amplifier stages, including the power amplifier, always exceeds the maximum output current. This leads to a very high energy consumption (and cooling might become a problem), but eliminates crossover distortions. Typical commercial amplifiers are what is called class A/B amplifiers, meaning, they would use a pretty high bias current to eliminate crossover distortions, but the bias current would still be less than the maximum output current to reduce the energy waste and cooling problems associated with pure class A amplifiers.
Why a high-efficiency machine is more desirable than a low- efficiency machine?
High-efficiency machines do more for less and are therefore more desirable than a low-efficiency machine.AnswerHigher efficiency means lower energy losses and, therefore, such machines are more economical than low-efficiency machines.
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What is class c tuned amplifier?
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.

Describe why a high-efficiency machine is more desirable thana low-efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
Are kicker amplifier better than alpine amplifier?
Thats really an opinion both brands are good amps and both are tested to show their correct wattage if not more than
Does Kenworth make a better car amplifier than Sony?
Sony has the best car amplifier on the market. These are typically more expensive as well.

What is a distribution amplifier?
A distribution amplifier is a device that increases the signal strength of signals it receives to levels larger than signal loss. It provides the signal to more than one isolated outputs.
