Common representations of digital logic functions and circuits are introduced. Number Systems, Arithmetic Operations, and Codes Basic definitions and common elements of binary logic systems are developed.After completing this text, the student should be prepared for a second (advanced) course in digital design, switching and automata theory, microprocessors or computer organization. Conveying binary signals within digital hardware utilizes a large number of data bus wires, and a large number of circuit element inputs. Logic gate: The digital circuit that can be analysed with the help of Boolean algebra is called a logic gate or logic circuit. The book can also be used for self-study or for review by practicing engineers and computer scientists not intimately familiar with the subject. Often times amateur mathematicians will confuse the subjects: Boolean algebra Logic Binary arithmetic Digital electronics and computation techniques Although the four subjects are closely related, they are not the same.

The main difference is that human beings can think independently, whereas computers can only answer questions that they are programmed for. Then binary numbers are commonly used in digital and computer circuits and are represented by either a logic 0 or a logic 1. Electrical signals such as voltages or currents prevail as analog signals having values over a given continuous range, say, 0 to 3 V, but in a digital system, these voltages are. A question asked to a human is analogous to entering a program into the computer using an input device such as the keyboard, and answering the question by the human is similar in concept to outputting the result required by the program to a computer output device such as the printer. What are the binary logic levels and high impedance states Logic gates are electronic circuits that regulate on one or more input signals to produce an output signal. Computer memory is conceptually similar to human memory.
The CPU of the computer is basically the same as the brain of a human. The basic blocks of a computer are the central processing unit (CPU), the memory, and the input/output (I/O). Any decimal number (base 10, with ten digits from 0 to 9) can be represented by a binary number (base 2, with digits 0 and 1). All computers, therefore, only understand binary numbers. Each of these discrete values is represented by the OFF and ON status of an electronic switch called a transistor.
A binary number has only two discrete values - zero or one. printed on integrated circuits), simple electronic representations of Boolean logic functions. The digital computer, more commonly called the computer, is an example of a typical digital system.Ī computer manipulates information in digital, or more precisely, binary form.
They are found in a wide range of applications, including process control, communication systems, digital instruments, and consumer products. Chapter 1 Introduction to Digital Systemsĭigital systems are designed to store, process, and communicate information in digital form.
