Consequently, a signal, represented as a function of one or more variables, may be defined as an observable change in a quantifiable entity.
A signal is a function that conveys information about the behavior of a system or attributes of some phenomenon.
To put it very generally, a signal is any time-varying physical quantity.
A digital representation can have only specific discrete values
A digital signal is a complex waveform and can be defined as a discrete waveform having a finite set of levels
A digital signal is a special form of discrete-time signal which is discrete in both time and amplitude, obtained by permitting each value (sample) of a discrete-time signal to acquire a finite set of values (quantization), assigning it a numerical symbol according to a code ... A digital signal is a sequence or list of numbers drawn from a finite set.
