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.
A signal is any kind of detectable quantity used to communicate information. An analog signal is a signal that can be continuously, or infinitely, varied to represent any small amount of change.
