Abstract

PURPOSE:To enable the following of any sharp change in a primary signal positively with an improved response speed by providing an acceleration detection circuit to output a signal for switching a clock pulse at a high speed with the phase of a primary signal changing at a high speed. CONSTITUTION:Analog switches (AS) 40A-J have nodes a-k of a resistance chain 16 connected to at least one comparator (CB) 42A or B. A direction discriminating circuit 46 obtains an upward or downward direction signal according to an output of the CB. A servo circuit 50 selects the analog switch AS corresponding to the direction signal in a specified sequence synchronizing clock pulses CP1-3. With such an arrangement, the nodes a-k are connected to at least one of CB 40A or B through the AS 40A-J to obtain an upward or downward direction signal with the circuit 46 according to the output thereof and in response to the signal, the ASs are selected with the circuit 50 in a specified sequence synchronizing a clock pulse while a signal is outputted to switch a clock pulse at a high speed from an acceleration detecting circuit 52 when changes in the phase of a primary signal reaches a high speed. This achieves a higher response speed with a greater switching speed of the ASs.
