  • Patent number: 4214177
    Abstract: A monitoring circuit for determining whether or not m out of n a.c. input signals meet at least one predetermined set of signal characteristics is disclosed. The circuit includes n input terminals, each for receiving a different one of the input signals being monitored. A logic circuit monitors the condition of the n input signals and generates either an a.c. or a d.c. output signal as a function of the condition of the input signals. A d.c. output signal is generated whenever m out of n input a.c. signals have maxima and minima which both lie above or both lie below a predetermined signal range corresponding to at least one of the preset signal characteristics. An a.c. output signal is generated whenever m out of n input signals have maxima and minima which respectively lie above and below the predetermined signal range.
