Some examples of signals are human voice, electrocardiogram, sign language, videos etc. There are several classification of signals such as Continuous time signal, discrete time signal and digital signal, random signals and non-random signals.
AC coupling will remove the DC component from a signal. For example, a sine wave with a mean of zero and an amplitude of +/-5 volts, as shown in Figure 2, would be unaffected by either a DC or an AC coupling. But a sine wave with a mean of 5 volts and an amplitude of +/-5 volts would be affected by an AC coupling but not a DC coupling.
