Amplification - The amplifier

For a complete study of amplifying circuits we advise the reader to refer to specialized textbooks on the subject. Here we will be looking at the main aspects of the functions and characteristics that relate to the correct calibration of an audio amplifying system.

Let's leave the circuitry needed to make an amplifier aside and consider the amplifier as a black box to which an input signal is applied and from which we obtain an output signal, whose amplification level corresponds to the aforementioned gain values:
