For example, if P is true then Not(P) is false So, if “today is Monday” is true then “Not(today is Monday)” is false. We often translate the logical expression into English as “today is Not Monday” and this makes it easier to see that it is false if today is indeed Monday...
This paper presents Shannon logic based QCA efficient full adder circuit for arithmetic operations. Shannon logic expression with control variables helps the designer to reduce hardware cost; using with minimum foot prints of the chip size. The mathematical models of the proposed adder are verified ...

There are many kinds of asynchronous logic. Data signals may use either "dual rail encoding" or "data bundling". Each dual rail encodedBooleanis implemented as two wires. This allows the value and the timing information to be communicated for each data bit. Bundled data has one wire for eac...
The inputs and output then take on values of 0 or 1. Sign in to download full-size image FIGURE 11. Symbol for an OR gate. The Boolean algebra expression used to define an OR gate is (6)X=A+B. The “+” sign denotes the “OR” operation rather than the usual addition. This ...

CML-ECL: Originally, the expression current mode logic (CML) had been coined to describe the logic gate arrangement achieved by stacking differential stages (series gating). Historical review of the high-speed IC issue Here the logic gates of the adder consist of fewer transistors, which have ...
The rule for writing down the algebraic expression corresponding to a map is that there will be one product term for each pair of adjacent 1 cells and a fundamental product for each 1 cell that is not adjacent to any other 1 cell. The fundamental products are written down according to the...
