Title: N-train pulse detector
Inventor: NAKAMURA TOYOAKI
IPC: H03K5/19
Filed: 1985-12-24
Abstract: PURPOSE:To reduce the number of pulse detection circuits by using a couple of gates so as to obtain AND and OR results and using a flip-flop so as to latch them thereby generating state information. CONSTITUTION:A couple of gates 11, 12, the 1st and 2nd flip-flops 13, 14 and a pulse detection circuit 15 are provided. A couple of the gates consist of an AND gate 11 and an OR gate 12, to which N-series of pulses are inputted at the same time to obtain the AND and OR logic. The 1st flip-flop 13 executes 1/2 frequency division by the output of the AND gate 11. The 2nd flip-flop 14 is operated by using an output of the OR gate 12 as a clock input and generates a pulse train detection signal and outputs from the output of the 1st flip-flop 13. A pulse detection circuit 15 detects a pulse train from the pulse train detection signal and recognizes it.
