Definition: parameter of a signal that represents information according to a rule

Note 1 to entry: For many signals the value of a given physical quantity is identical with the value of the information parameter. In this case it is usual, for the sake of simplicity, to speak of the “value of a signal”.

Note 2 to entry: For an amplitude-modulated alternating voltage signal the information parameter of the signal is the relationship between the actual amplitude to that amplitude the voltage would have without amplitude-modulation. For a duration- or position-modulated pulse signal the duration of each pulse or the position of each pulse within the pulse period respectively is the information parameter of the signal.

Note 3 to entry: This entry was numbered 351-21-52 in IEC 60050-351:2006.
