Amplifier transfer function

Amplifier transfer function is a mathematical expression that describes the relationship between an amplifier's input signal and its output signal. It represents how the amplifier modifies the amplitude and phase of the input signal as a function of frequency.

Key concepts:

Input signal: The signal being fed into the amplifier.

Output signal: The amplified signal produced by the amplifier.

Frequency: The rate at which the signal oscillates, measured in Hertz (Hz).

Amplitude: The magnitude of the signal, measured in volts (V).

Phase: The relative timing of different frequency components of the signal.
