Abstract

Problems associated with variations in pulse amplitude due to, for example, intersymbol interference, which can otherwise create problems in timing recovery circuits using the edges of the pulses are overcome by basing timing recovery on the center of the received pulses rather than the leading or trailing edges. Although jitter due to variations in pulse amplitude is not eliminated, timing recovery is improved because jitter due to variations in the center of the pulse are less than is jitter in the edges of the pulse.
