Block Diagram of Audio Amplifier System. This block diagram of an audio system shows all the stages from microphone to speaker and follows the design of a typical PA system. The links between the subsystems are P, Q, R, S, and it is important to understand their nature, because they are responsible for minimising signal losses in a well-designed system.

A simplified block diagram with some additional information is given below. As you see in the above figure there are four blocks. Input Stage: The main function of Op Amp is, at first it creates a difference between the two input signals and then amplify the differentiated signal. So in the Input Stage, the differential amplifier creates the ...

Audio Amplifier: it will amplify the audio signal to high power. (This part may be divided into more blocks, like the amplifier system above.) Loudspeaker: converts electrical signals into sound; Regulated Power Supply System. Transformer reduces the voltage from AC 220 volts to a low voltage AC. Rectifier converts AC to DC voltage. But it is ...
Introduction to Functional Block Diagram (FBD) | EdrawMax
https://www.edrawsoft.com/article/what-is-functional-block-diagram.html
A Functional Block Diagram (abbreviated as FBD) is a graphical representation of a functional process via blocks and diagrams that is easier for a reader to understand and interpret. An FBD helps us determine the function between output variables and input variables via a set of rudimentary blocks and diagrams that are connected with arrows known as “connections.”
