8085 Microprocessor

The most important technological invention of modern times is the “microprocessor”. A microprocessor is a multiple purpose programmable clock driven,

Multiplexing means sharing. A digital multiplexer (MUX) is a combinational circuit that accepts several data inputs and allows only one

The availability of a large variety of codes for the same discrete elements of information results in the use of

Half Adder The half adder is an arithmetic circuit used to perform the addition of two single bits. The two

A combinational circuit consists of an interconnection of logic gates, whose outputs at any instant of time are determined from
