PROBLEM TO BE SOLVED: To provide a pulse logic circuit capable of using a pulse train for an information transmission medium and dealing a pulse itself as a control signal. SOLUTION: In the pulse logic circuit for receiving the pulse train configured such that one of two voltage levels is made a logical level 1 and the other is made a logical level 0, when a pulse is present at a desired time or a desired time interval, the logical value 1 is given to the time or the time interval, and when no pulse is present, the logical value 0 is assigned, a logic AND with a suppression input terminal attached thereto for suppressing an output when the logical value is 1 comprises a P type MOS transistor 10 and an N type MOS transistor 11, and an output (pulse train b) of NOT arithmetic operation for inverting the logical value 0 in the absence of the pulse and providing the logical value 1 indicating the presence of the pulse is given only to the suppression terminal attached logic AND.
