An electronic system parameter, such as time deviation (TDEV), is measured by reference to an input series of data samples received and processed to produce in real-time first and second time-varying series of measurements for the parameter.
Timing errors in digital transmission systems, such as maximum time interval error, are measured with data samples processed in a first stage to produce in real-time a first, time-varying series of measurements for a given parameter over observation intervals of a first magnitude. Each
