Amplifiers 1 E. COATES 2007 -2012 Amplifiers Introduction to Amplifiers An amplifier is used to increase the amplitude of a signal waveform, without changing other parameters of the waveform such as frequency or wave shape. They are one of the most commonly used circuits in Electronics and perform a variety of functions in a great many electronic systems. The general symbol for an amplifier is shown in Fig The symbol gives no detail of the type of amplifier described, but the direction of signal flow can be assumed (as flowing from left to right of the diagram). Amplifiers of different types are also often described in system or block diagrams by name. Amplifiers Module 1 What you ll Learn in Module 1 Section amplifier Basics.
