Combinational logic uses two or more logic gates to perform a more useful, complex function.. A digital circuit is one in which only two logical values are present.. Typically, a signal between 0 and. 0.5 . volt represents one value (e.g. binary 0) and a signal between. 1 . and. 1.5 . volts represents the other value (e.g. binary 1).. M. AL- . Towaileb. 1.

What is Boolean Algebra ?. Boolean Algebra is a mathematical technique that provides the ability to algebraically simplify logic expressions. These simplified expressions will result in a logic circuit that is equivalent to the original circuit, yet requires fewer gates.. Algebra. Huntington’s Postulates. Truth Tables. Graphic Symbols.

Microchips (processors) . do exactly whatever instructions are fed into it, and that too without a single mistake.. Boolean . Logic was first introduced by George . Boole. The . basic . Boolean . operation can be further mapped into operations using bits and bytes. The most basic idea of Boolean Logic can be explained using logic gates. When the logic required becomes complex, these logic gates can be combined into more complex forms to get the required output. We have seen how we can represent information in binary, now we will explore. Why we use binary. How to compute using binary. How to implement binary operations using Boolean algebra (such as binary addition).
