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.
Quite simply, coupling is the transfer of energy from one medium to another, for example, from a metallic wire to an optical cable. This transfer of energy may be desirable or undesirable. DC coupling allows both AC (alternating current) and DC (direct current) signals to pass through a connection. AC coupling allows only AC signals to pass through a connection. A DC source can be considered to be like a battery, in that there is a constant negative charge from the batteryâs negative terminal to the positive terminal. An example of such a source is shown in Figure 1.
