Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.
Students read about the three main classes of amplifiers and view graphical representations of the collector current and circuit.
Students read an explanation of the common-source and source-follower amplifiers. Gain formulas are developed and an example is given.
