ABSTRACT:
A comparator circuit for two multi-digit binary codes, particularly binary numbers, in which a series circuit is formed by n number of majority decision elements connected in series, each of which has three inputs, the characteristic information of the first binary number being supplied to a respective input in a negated manner, and the information of the second binary number to another respective input in a non-negated manner. In one embodiment, an evaluation circuit for a qualitative comparison result utilizes a test pulse in conjunction with the binary numbers, which pulse is supplied to the last element of the series connected elements. Depending on the embodiment, the qualitative comparision result may be read out either in response to a test pulse or continuously.
