Previously a continuous signal or values are used represent data which is known as Analog signal. In modern computing sectors, data representation changes to discrete/non-continuous signals or values(only 0 or 1) which is known as Digital. Here, the overall information is encoded in a sequence of bits where every bits represents only two states(1 for high and 0 for low) of the information. Having a solid understanding of digital logic enables us to troubleshoot and debug digital systems, ensuring their proper functioning. It also opens up opportunities for innovation and the development of new technologies. Boolean algebra is a mathematical system used to analyze and simplify logical expressions.
Written Boolean Logic
They are used in computer processors, memory units, communication systems, and various other electronic devices. Logic gates are also used in control systems, robotics, and automation, enabling precise and efficient operations. This book is designed for use in an introductory course on digital logic design, typically offered in computer engineering, electrical engineering, computer science, and other related programs. This book makes extensive use of animation to illustrate the flow of data within a digital system and to step through some of the procedures used to design and optimize digital circuits. From the above truth tables of Ex-OR & Ex-NOR logic gates, we can easily notice that the Ex-NOR operation is just the logical inversion of Ex-OR operation.
Functions of Different Logic Gates
Understanding the basics of digital electronics, including logic gates, Boolean algebra, truth tables, and different types of circuits, is crucial for anyone working in the field of electronics. Digital logic is the foundation of modern computing and electronics. It involves the study of logic gates, Boolean algebra, truth tables, and the design of combinational and sequential circuits. While it may seem intimidating at first, with the right approach and resources, learning digital logic can be an exciting and rewarding journey. As mentioned before, electrical and computer engineering is often based on digital logic design.
Combinational circuits (II)
When a computer's "speed" is cited, this is the value in question. It is possible to design "asynchronous" sequential circuits, which do not rely on a synchronized global clock. However, those systems pose great difficulties, and we won't be discussing them here.
Conversion of Flip-Flop
Truth tables are essential for understanding the behavior of logic gates and designing digital circuits. Digital electronics is a branch of electronics that deals with the study and application of digital signals and systems. It involves the use of logic gates, Boolean algebra, and truth tables to design and analyze digital circuits. These circuits can be either combinational or sequential in nature. Digital logic is a fundamental concept in the field of computer science and electrical engineering.

These symbols typically consist of a combination of lines, curves, and circles, which represent the different input and output connections of the NAND gate. Understanding these symbols is essential in interpreting and designing digital logic circuits that involve NAND gates. By grasping the concepts of logic gates, Boolean algebra, and truth tables, we can design and analyze complex digital circuits. These circuits are the building blocks of modern devices like computers, smartphones, and digital appliances.
Sequential circuits (II)
Digital logic circuits can be broken down into two subcategories- combinational and sequential. Sequential circuits have a clock signal, and changes propagate through stages of the circuit on edges of the clock. An AND gate is a digital circuit that has two or more inputs and produces an output, which is the logical AND of all those inputs. It is optional to represent the Logical AND with the symbol ‘.’.
One of the most important branch of Electronic and telecommunication Science sector is Digital electronics(logic). Digital logic is mainly used for data(must be digital information) representation, manipulation and processing of using discrete signals or binary digits (bits). It can perform logical operations, data retrieval or storing and data transformation by analyzing logical circuit design. To learn digital logic design, you can start by studying Boolean algebra, truth tables, and logic gates. Online tutorials, textbooks, and practical projects can also help in gaining proficiency.
They are used in the design of microprocessors, memory units, arithmetic circuits, and control systems. Logic gates are also utilized in digital communication systems, where they play a crucial role in encoding and decoding information. One of the key reasons why digital logic is important is its ability to represent and process information in a reliable and efficient manner. Digital circuits can store and transmit data without loss or degradation, making them ideal for applications that require high accuracy and precision. From simple calculators to advanced computer systems, digital logic is at the core of their functionality. This is great to create complex logic circuits and can be easily be made into a subcircuit.
A truth table shows all the possible input combinations and the definite result of each of them. Logic gates can be implemented using various technologies, such as transistors, diodes, or even mechanical switches. Transistors are commonly used to build logic gates due to their small size, low power consumption, and high switching speed. The combination of these three values determines the highest clock speed a device may use. Typically, a sequential circuit will be built up of blocks of combinational logic separated by memory elements that are activated by a clock signal.
The truth table of Ex-OR gate is same as that of OR gate for first three rows. That means, the output (Y) is zero instead of one, when both the inputs are one, since the inputs having even number of ones. If at least one of the input is ‘1’, then the output, Y is ‘0’.
Digital transformation started in the late 20th century with the advent of computers and the internet, but it has gained significant momentum in recent years. When you purchase a Certificate you get access to all course materials, including graded assignments.

D flip-flops are simple -- upon a clock edge (normally rising, although they can be found with a built-in inverter to clock in on the falling edge instead), the input is latched to the output. NOR gate operation is same as that of OR gate followed by an inverter. NAND gate operation is same as that of AND gate followed by an inverter. Here A, B are the inputs and Y is the output of two input NAND gate.
They use the specific characteristic of these logic functions to build complex circuits for electronic components. The end result of the logic design and implementation process are circuit boards and chips (i.e. microchip processors) housing the logic gates and functions. Each component has a unique set of characteristics defined by the logic, such as power, input, protocol, and logic function. These basic logic gates can be combined to create more complex circuits known as combinational circuits.
