Abstract
A reference signal of reference pulses occurring at a uniform reference pulse rate is received. An error event signal of error event pulses occurring at a variable error event pulse rate corresponding to a rate of detected error event occurrences is received. An integrator output signal is produced from the reference signal and the error event signal. The integrator output signal has a value that approaches a first boundary threshold when the reference pulse rate exceeds the error event pulse rate and approaches a second boundary threshold when the error event pulse rate exceeds the reference pulse rate. A decision signal is set to a first value in response to a determination that the value of the received integrator output signal meets a first decision threshold and set to a second value in response to a determination that the value of the received integrator output signal meets a second decision threshold.
