Everything about Complex gain

In electronics, the concept of gain is the amount a electrical system changes the magnitude of an input signal. The complex gain is the effect that circuitry has on not only the amplitude but also the phase of a sine wave signal. Such an input signal can pass through an electric circuit that increases the magnitude and for example take differing amounts of time, or intentionally be phase shifted with electrical components. The term complex arises from complex numbers and there usefulness in expressing wave phenomena via Euler's formula. Wikipedia →
