Is amplifier gain constant?

The amplifiers gain, ( A ) should remain constant for varying values of input signal. Gain is not be affected by frequency. Signals of all frequencies must be amplified by exactly the same amount. The amplifiers gain must not add noise to the output signal.

What happens if the gain of the amplifier is not properly maintained?

Most amplifiers are designed to be linear. That is, they provide constant gain for any normal input level and output signal. If an amplifier's gain is not linear, the output signal can become distorted.

What is loop gain in control system?

In electronics and control system theory, loop gain is the sum of the gain, expressed as a ratio or in decibels, around a feedback loop.

What causes clipping of an amplifier output signal?

Clipping occurs when more power is required from an amplifier then it is able to deliver. Once the maximum amount of power supply voltage has been reached, it becomes impossible to amplify the incoming signal without compromising its form. This means that the signal is amplified but in a very distorted form.
