Title: Discriminating circuit
Inventor: TANAKA KAZUYUKI
IPC: H03K19/0175
Filed: 1986-12-22
Abstract: PURPOSE:To prevent an erroneous discrimination by discriminating a state of an input terminal by a result of having brought a sampling signal outputted by a short period by a repeated pulse signal, to sampling at least two times. CONSTITUTION:In accordance with D-type FFs 2, 4, FFs 22, 23 are provided, and to a clock terminal C, sampling signals SP1, SP2 of a shorter period than a repeated pulse K, and its inversion signals are applied from a sampling signal generating circuit 9. Subsequently, when a contact 11 of a switch SW is connected to a terminal 12 of an H level, an amplifier 6 outputs an H level, each FF outputs an H level to a terminal Q, and only a terminal A1 becomes an H level. When the switch SW is connected to a low level contact 13, each FF outputs an L level to the terminal Q, and a terminal A3 becomes an H level. When the switch SW becomes an open state, the pulse signal K is amplified 5, 6 and inputted to each FF, and only a terminal A2 outputs an H level. In such a way, even if the terminal is in an open state, an erroneous decision caused by a noise is decreased remarkably.

Abstract: PURPOSE:To shorten a busy state based on the uninput of a dial by supervising time until the dial is inputted after on-hook, releasing off-hook in a connection device when it has exceeded a prescribed time and setting a system in a handset waiting state. CONSTITUTION:When the dial action based on dial input from a handset 1 is not performed within a prescribed time To after off-hook, a timer circuit 27 detects it and generates an output for a control part 26. It operates a hook- switch 25 and sets it to be the on-hook state, operates an alarm generation circuit 28 and generates the alarm sound of a prescribed frequency. A control part 18 disconnects the power of a transmission part in a radio transmission/ reception circuit 13 by waiting for the termination of the signal of alarm sound when it detects the signal of alarm sound in the output of a sound circuit 23. At the same time, it operates a reception part at the intervals of a prescribed time and sets it to be a receptio-waiting state. Thus, the continuation time of busy state based on the uninput of the dial can be set to minimum after off-hook.
