Jitter measuring equipment includes timing recovery circuitry with a first filter having a Gaussian-family response to enable the equipment to tolerate relatively long runs of data symbols of a single value without affecting the accuracy of timing of clock recovery. Potential distortion of the jitter measurement which could arise from this amplitude response characteristic is alleviated by applying the demodulated baseband signal, prior to jitter measurement, to a demodulated filter having an amplitude response characteristic that is approximately the inverse of the response of the first filter.
