The so-called "Class-A" amplifier is the configuration with the least distortion.
Active stages are biased to operate within the linear portion of their characteristics,
and drive is controlled to avoid saturation or cutoff. Any remaining distortion is due
exclusively to unavoidable non-linearities in components.

What contributes harmonic distortion in amplifier?
+ve feedback
Which distortion is least objectionable in audio amplifier?
phase...
What are the least efficient of class of amplifier?
class b amplifiers as for class b amplifier the 'Q' point is near to cut of region.
Class c amplifier advantage?
Efficiency of class C amplifier is approximately 100%.
Which class of amplifiers have minimum distortion?
A:class 'a'
In which amplifier occurs Maximum distortion?
CLASS -C amplifier is having high ditortion due to which they are not used in audio frequency work
How much money does a Class T amplifier cost?
A Class T amplifier will typically cost around $20 to $40. The Class T amplifier is a small amplifier that produce a great amount of audio volume for it size.
Which class of amplifier have maximum distortion?
Class C since output cycle is less than 90 degrees for a full input. But it has highest power gain going upto 98%. And the exact term used for distortion is Total Harmonic Distortion since the distortion produced will be in multiples of the fundamental frequencies.
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 b power 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 contributes harmonic distortion in amplifier?
+ve feedback
What is a class d monoblock amplifier?
A class D monoblock is a highly efficient and more powerful amp suitable for sub-woofers. But they may not be that suitable for speakers/tweeter due to high distortion.
How do you get a clean sound from your guitar?
By turning off the distortion on your amplifier
Which distortion is least objectionable in audio amplifier?
phase...
What is use of negative feedback in amplifier?
Reduce the distortion in output signal.
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 is zero cross distortion in a signal?
Crossover distortion is a type of distortion which is caused by switching between devices driving a load, most often when the devices are matched. It is most commonly seen in complementary, or "push-pull", Class-B amplifier stages, although it is occasionally seen in other types of circuits as well.
