Abstract: PURPOSE:To prevent to generate a steady phase error, to minimize extremely the influence of a quantitizing error and to obtain an phase comparing system easy to form an IC by measuring a phase difference with a digital system, and correcting a quantitizing error to the measured phase difference with the analog system. CONSTITUTION:When the phase of RD DATA proceeds, in a rise of RD DATA, a comparing wave CW is between Low, and an F/F5 generates a pulse from the rise of RD DATA to the next rise of the comparing wave. When the phase of RD DATA is delayed, an LS191 is counted up by fc while the comparing CW is HIGH, and when the RD DATA does not exist, a Low is Loaded by the fall of the comparing wave and while the comparing wave is Low, the output of the LS191 goes to all zero. While the LS191 is counted up, the rise of the RD DATA exists, an F/F1 is inverted, the counting down is started, and simultaneously the pulse is generated from the F/F4, the LS191 goes to be all zero, and then, the F/F4 is cleared and the pulse is stopped. Thus, the phase error can be made very small without generating the steady phase error.
