ONE TRACK JUMPING CIRCUIT BY USING SWITCHING PULSE

摘要

A circuit correctly jumps a track of a compact disk player by using a switching pulse. The circuit comprises a data selection section (1) for selecting the serial data (SD) from a microcomputer (10), a flip-flop circuit (2), including two inverters (IV1,IV2) and six flip-flops (F1-F6), for changing the output by the switching pulse (SP), and a logic circuit (3) for producing the tracking mode switch signals (TM1-TM6) by combining the output of the flip-flop circuit.
