A signal coded in a binary way
The digital signal corresponds to binary or Boolean logic, i.e. a coding system wherein only two opposite positions are admitted as, for example, yes/no; or true/false, which can be represented by 1/0 or pulse/no pulse.
Digital signals imply necessarily a discrete coding, in opposition to continuous representation.
