Abstract

Described below is a time phase recovery circuit specially made as a digital LSI-circuit. The time phase recovery circuit has a first device (22) for withdrawal of a digital time signal (St) from a received analogue input signal (Ain), an extra device (55) for detection of a virtual zero-crossing at the digital time signal (St) synchronized with a sampling signal (Ss) and a third device (53) for carrying out a phase shift with respect to the sampling signal with the purpose of , in a very short time, harmonizing the time signal to the frequency of the virtual zero-crossing.<IMAGE>
