degree of isochronous distortion
In data transmission, the ratio of (a) the absolute value of the maximum measured difference between the actual and the theoretical intervals separating any two significant instants of modulation (or demodulation) to (b) the unit interval. Note 1: These instants are not necessarily consecutive. Note 2: The degree of isochronous distortion is usually expressed as a percentage. Note 3: The result of the measurement should be qualified by an indication of the period, usually limited, of the observation. For a prolonged modulation (or demodulation), it will be appropriate to consider the probability that an assigned value of the degree of distortion will be exceeded.
