Title: Input signal interruption detection circuit
Inventor: MAEDA MASAAKI
IPC: H04B3/46
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To prevent mis-release of an alarm by comparing a prescribed period with a significant level period denoting the presence of an input signal by a comparison result by a comparator means and eliminating noise when the significant level period is shorter than the prescribed period. SOLUTION: A setting time based on a width of a signal 9, that is, on an internal time constant is set matching a border between a width of a signal 1 generated by noise and a width of a signal not being noise. That is, it is set that a significant level period of a signal 8 from an inverting circuit 38 generated by a noise signal is included in a signal level period of the signal 9 and a significant level period of the signal 8 from the circuit 38 generated by a signal not being the noise is at the outside of the significant level period of the signal 9. When the signal 1 is received as a signal not being noise, a signal 12 goes to an H level and an alarm signal is outputted. Thus, the instantaneous noise component outputted from a comparator 25 is completely eliminated by a noise signal elimination means 31 to prevent mis-release of alarm due to noise.
