Study Notes

Amplifiers can amplify small input signals to larger output signals.
Amplifiers contain an amplifying device with two input terminals and two output terminals.
The gain of an amplifier is the difference between the input and output signals.
There are three types of amplifier gain: voltage, current, and power.
The gain of an amplifier can be expressed in decibels (dB).
The bel is a logarithmic unit of measurement with no units.
The -3dB point of an amplifier is called the half-power point.
Amplifiers can be classified as either voltage or power amplifiers.
Base biasing is required for a transistor to operate within its "Active Region".
Base bias voltage added to the input signal allows the transistor to reproduce the full input waveform at its output with no loss of signal.
