Combinational Logic Circuits (Adders, Multiplexers, Demultiplexers etc)

Combinational Logic CircuitsUnlike sequentcial logic blocks whose outputs are dependant on both their present inputs andtheir previous output state giving them some form of Memory, the outputs of CombinationalLogic Circuits are only determined by the logical function of their current input state, logic "0" or logic "1", at any given instant in time as they have no feedback, and any changes to the signals being applied to their inputs will immediately...

Boolean Algebra and logic gates

INTRODUCTION The process of converting control objectives into a ladder logic program requires structured thought. Boolean algebra provides the tools needed to analyze and design these systems. BOOLEAN ALGEBRA The techniques can model a logical system with a single equation. The equation can then be simplified and/or manipulated into new forms. The same techniques developed for circuit designers adapt very well to ladder logic programming. Boolean...

Functional units of computer system,control unit and arithmetic logic section

FUNCTIONAL UNITS OF A COMPUTER SYSTEM Digital computer systems consist of three distinct units. These units are as follows: Input unit Central Processing unit Output unit these units are interconnected by electrical cables to permit communication between them. This allows the computer to function as a system. Input Unit A computer must receive both data and program statements to function properly and be able to solve problems. The method of feeding data and programs to a computer is accomplished by an input device. Computer input devices read...

Introduction to Computer Organization & Architecture:

Computer architecture refers to those attributes of a system visible to a programmeror we can say those attributes that have a direct impact on the logical execution of a program. Computer organization refers to the operational units and their interconnection that realize the architecture specification.  A system consist of set of objects or components such as monitor,keyboard,cpu and softwares as well. so designer analys it as structure and function  Structure it is the arrangement of components Function  it is the operation...
