ABSTRACT:
A clock timing recovery circuit for recovering the clock timing from a baseband signal obtained by detection of a received signal. The clock timing is rapidly established using a clock signal which has been phase-shifted from the desired clock timing to sample the baseband signal, and by obtaining the optimum phase from the sampled signal obtained as a result. A clock-timing recovery circuit according to this invention does not require oversampling and provides easy optimization of circuit constants.
