Title: Signal input detecting circuit
Inventor: KOBA TAKAHARU
IPC: H04Q9/00
Filed: 1987-09-29
Abstract: PURPOSE:To remove the influence of a noise and to detect the pulse of the width of a constant length without fail by starting the count of a first clock signal with a count means when an external signal is inputted and executing the reset of the count means with a signal stopping time detecting means in case of the external signal due to the noise. CONSTITUTION:While the external signal is inputted, an output '1' is outputted from OR gates 24-26 to a counter 13 and a first clock signal CLK is counted by the counter 13. When the external signal has the character of the noise of the short width, the external signal is not inputted immediately. Then, it is transmitted that there is no input of the external signal to data flip-flops DFF21-23 by a CLK2 and a Q output successively reset binary flip-flops BFF14-16. Normally, the pulse width of the noise is enough short to the pulse width of a reader pulse. Thus, before the Q output of the counter 16 goes to '1', the counter 13 is reset and the noise pulse is not detected by a detecting means 18.
