摘要： A transition enhancement apparatus includes a tapped delay line (38) to which input signal is applied. Respective taps of the delay line are coupled to respective input terminals of a multiplexer (40). The multiplexer (40) includes control circuitry (9) which is programmed to sequentially pass signal from respective ones of the taps according to a plurality of tap selection patterns. A signal transition detector (10,12), responsive to the signal applied to the delay line, measures a feature of a detected transition, and responsive thereto conditions the control circuitry (9) of the multiplexer (40) to pass signal according to one of the tap selection patterns.
