ABSTRACT:
A comparator and a method for comparing one digital signal composed of n bits to a second digital signal also composed of n bits. The comparator includes a predetermined number of logic levels. The comparator samples and compares selected bits of the two signals in any order and applies Boolean algebra operations to the signals without reference to any comparison of any other bits of the signals. The comparator provides an output signal of one logic level if one signal is greater than the other, and of a second logic level if the one signal is less than or equal to the other signal.
