Amplifier power is a circuit of electronics that is used to strengthen the power (or energy in general). In the field of audio, amplifier will amplify the sound signal (which has been expressed in the form of electric current) on the input it into electric current is stronger at the output. The amount of strengthening is often known by the term gain. Value of the gain is expressed as a function of frequency is called the transfer function.
So the gain is the result of the power output (Pout) and power at the input to its function in the form of frequency. The size of the gain, (G) is usually the Decibel (dB).
