The analogue subsystem - 3:
BUILD A UNIVERSAL MULTI-GAIN ANALOGUE AMPLIFIER
Amplifiers are used to boost weak electrical signals to higher levels. For example, a voltage amplifier will boost a weak voltage signal to a higher voltage level so that it can be displayed on a meter, viewed on a cathode ray oscilloscope (eRO), written on a paper chart recorder, or processed by an analogue-to-digital converter for input to a computer.
