Title: Pulse discriminating circuit
Inventor: SAITO NOBORU
IPC: G06F9/46
Filed: 1988-09-30
Abstract: PURPOSE:To reduce the extraction of noise and to reduce the size and price of a device by connecting an input inhibiting circuit and a memory circuit between an input terminal and a detecting circuit and preparing one interruption factor analyzing circuit and an interruption signal informing line. CONSTITUTION:When B1 is raised prior to the end of A1, the outputs A2, B2 of an one-shot circuit 5 are turned to '0' for one clock respectively after ending the A1 and B1. A signal alpha3 is AND between the A2 and B2 and means an interruption inhibiting signal. The output A4 of a NAND gate 8 is obtained by inverting the A1 and the B4 is held at '1' during the '1' of the signal alpha3 after inverting the B1. The output alpha5 of an AND gate 9 is AND between the outputs A4, B4 of the NAND gates 8 in both the circuits A, B, temporarily decayed when the A1 is raised, inverted when a clock is initially raised after ending the A1, and then decayed again when the clock is raised again. Consequently, noise extraction can be reduced.
