Amplification

In this section we'll be exploring the concept of amplification and its many involved features, which change depending on circumstances. The basic idea is that we can act upon the quantities which characterize the signal, such as the amplitude and power, and increase them (indeed this is what amplification consists in) to fulfill our desired aims. It is, however, important to understand that not all signals can be amplified in the same way, and above all, that each and every time we are working with quantities and configurations that are different to one another. If we analyse the route a signal takes, from the source (i.e a microphone) to its final destination (i.e a loudspeaker) we will understand the fundamental differences between each situation.
