Controls Amplifier To Block Diagram. You only need a few capacitors to make a decent stereo amplifier out of it. It is so simple to build that i put it together on a stripboard in just a few hours.

Tone and volume controls adjust the nature of the audio signal. Amplifiers as parts of large electronic systems for example look at the block diagram of an analogue tv receiver in fig 1 0 2 and see how many of the individual stages shaded green that make up the tv are amplifiers. The power supply not shown is connected to the pre amplifier and power amplifier blocks.

Pre amplifier amplifies the small audio signal voltage from the microphone.

Amplifiers of different types are also often described in system or block diagrams by name. Step 1 use rule 1 for. Figure 6 shows a typical cfb block diagram. Voltage amplification stage the input signal to the amplifier from the source will be generally in the mill volt range and it is very weak to drive the succeeding stages.
