Logic gates are frequently used in digital electronics, particularly in implementing mathematical operations. Though in principle there are two basic mathematical operations; addition and subtraction, however, it may be only addition if numbers are defined as positive and negative. Addition of a ...

2. Fundamentals of Logic gates 2.1 LOGIC GATES We have seen that the foundation of logic design is seated in a well defined axiomatic system called Boolean algebra, which was shown to be what is known as a “Huntington system”. In this axiomatic system the definition of AND and OR ...
A wide gate operation margin, multiple logic function capability, and a small gate size are among other important factors in the evaluation of the JJ logic gates. The small gate size is, in particular, very important because it make it possible to densely pack the logic gates and to shorten...

An opto-electronic XOR gate includes a pair of diode type light sources connected back to back in parallel by a pair of input leads to which first and second electronic logic signals are applied. With only one logic signal in the high state, one of the diode-type light sources is forward...
