Abstract
A digital synchronization operation circuit synchronizes a pulse train with horizontal synchronizing pulses contained in a received standard television signal which, after being demodulated in the television receiver, is present as the composite color signal and which is fed to an analog-to-digital converter clocked by a clock signal. The digital synchronization separation circuit has an improved phase resolution such that the phase resolution is greater than the resolution provided by the pulse width of clocking signals.
