Title: Operation error preventive incoming detection circuit
Inventor: NAGANAWA HIROICHI
IPC: H04M1/64
Filed: 1980-03-24
Abstract: PURPOSE:To obtain an incoming detection circuit which is able to prevent an operation error caused by an intermittent noise or continuous noise, etc. CONSTITUTION:When a bell signal of 16Hz comes in, the relay R is operated, an input of the AND gate 11 is made ''0'' by its contact (r), the clear terminal CR of a hexadecimal counter 8 becomes ''0'', the hexadecimal counter 8 becomes ready for operation, and starts to count continuous pulses P of 0.1 second period applied to the clock input terminal. If said bell signal SIG is generated by a single noise pulse, and the relay R has been released before the pulse 8 is counted 8 times, the hexadecimal counter 8 is released and a detection error of incoming can be prevented. Also, when the counter 8 has counted the pulse P 8 times, the D terminal of 8 becomes ''1'', therefore ''0'' is applied to the clear terminal of the counter 8 through the NOR gate 12, the counter concerned continues the count operation in order to prevent an operation error due to continuous noise.
