Title: Pulse train generating circuit
Inventor: KOIDE SATORU
IPC: H03K3/78
Filed: 1984-04-16
Abstract: PURPOSE:To obtain a pulse train having a desired period and select the desired number of pulses by using only plural cascaded one-shot flip-flops (FF), a counter, and a decoder. CONSTITUTION:A trigger pulse P0 is inputted to a terminal A1 of a one-shot FFOS1 to reset the counter C, and the OS1 is set when the pulse falls and then reset automatically a specific time later to set an OS2. This state is held for the specific time and then reset automatically, and the OS1 is set again. Thus, the OS1 and OS2 generate pulse trains from output terminals P1 and P2. When the contents of the counter C attain to (n), an output N is generated and the OS1 stops the pulse generating circuit. Namely, the pulse train outputs P1 and P2 allow the OS1 and OS2 to generate pulses with a specific period as many as specified by the counter C.
