ABSTRACT:
A logic device for use with data signals having a continuously or semi-continuously varying waveform of substantially fixed frequency. The device provides a logical output from at least one of the data inputs and comprising a first pair of inputs each to receive a data signal having one of a predetermined set of values representing analog, discrete, or digital states. A combiner stage is used to combine the inputs and produce a signal therefrom. A filter stage is utilized to receive the signal and produce a conditioned signal representative of one of a pair of binary states. The conditioned signal is combined with a second control input. The resultant signal is passed to an output.
