The basic digital electronic circuit that has one or more inputs and single output is known as Logic gate. Hence, the Logic gates are the building blocks of any digital system. We can classify these Logic gates into the following three categories.
The Role of Digital Logic in Technology and Business
The NOT operator, on the other hand, simply negates the input value. On the other hand, sequential circuits have memory elements that store information and produce outputs based on both the current inputs and the stored information. Sequential circuits are widely used in applications such as memory units, counters, and flip-flops. In digital transformation, logic gates are the fundamental components that enable the processing and manipulation of digital data. They form the building blocks of digital systems and play a crucial role in transforming businesses and industries.
Useful Resources for Learning Digital Logic
The teachers may incorporate this software in their courses like Digital Logic and Computer Design, Computer Architecture, Computer Organization and Embedded Systems. Digital logic is crucial in modern technology as it forms the foundation for designing and implementing digital systems, such as computers, smartphones, and other electronic devices. As you can see, the output is only true (1) when both inputs are true (1), and false (0) otherwise. Truth tables provide a systematic way to analyze and understand the behavior of logic gates and circuits.
Digital Logic Basics: Understanding the Fundamentals
Our team collaborates to create high-quality, well-researched articles on a wide range of science and technology topics for the TechieScience.com website. Each logic family has its own advantages and disadvantages, making them suitable for different applications. The choice of logic family depends on factors such as speed requirements, power consumption, noise immunity, and cost.

There is a sixth element in digital logic, the inverter (sometimes called a NOT gate). Inverters aren't truly gates, as they do not make any decisions. The output of an inverter is a 1 if the input is a 0, and vise versa. This NOT gate produces an output (Y), which is the complement of input, A. In earlier chapters, we learnt that the Boolean functions can be represented either in sum of products form or in product of sums form based on the requirement.

At its core, Boolean logic deals with binary values, which can be either true or false, represented as 1 or 0, respectively. These binary values are used to represent the states of electronic switches, which are the building blocks of digital circuits. Take your time, practice regularly, and don’t hesitate to seek help when needed.
Combinational circuits (II)
So, we can implement these Boolean functions by using basic gates. Let’s take a closer look at how logic gates work and how they can be implemented in circuits. Click on "v More" to read the purpose of this module Arithmetic circuits are an essential part of many digital circuits and thus deserve a particular treatment. The truth table of Ex-NOR gate is same as that of NOR gate for first three rows. That means, the output is one instead of zero, when both the inputs are one. Here A, B are the inputs and Y is the output of two input Ex-OR gate.
NOT gate
They are electronic devices that perform logical operations on one or more binary inputs to produce a binary output. There are several types of logic gates, including AND, OR, NOT, NAND, NOR, XOR, and XNOR gates. Understanding logic gates is fundamental to working with digital logic.
When did digital transformation start?
Therefore, the output of Ex-NOR gate is ‘1’, when both inputs are same. Its function is same as that of NOR gate except for some cases, when the inputs having even number of ones. Below figure shows the symbol of Ex-OR gate, which is having two inputs A, B and one output, Y. Therefore, the output of Ex-OR gate is ‘1’, when only one of the two inputs is ‘1’. Its function is same as that of OR gate except for some cases, when the inputs having even number of ones. The following figure shows the symbol of NOR gate, which is having two inputs A, B and one output, Y.
Digital devices that use digital logic design are implemented across a variety of fields and applications. You will find them being used in medical and aviation equipment, in military navigation systems, as well as in everyday consumer products such as your humble smartphone. These operators allow us to combine and manipulate binary values to perform logical operations. For example, the AND operator returns true (1) only if both inputs are true (1), while the OR operator returns true (1) if at least one input is true (1).
Design circuits quickly and easily with a modern and intuitive user interface with drag-and-drop, copy/paste, zoom, and more. When your code reaches a while() statement, the program evaluates the conditional ("Is it windy?") and, if it evaluates to "TRUE", executes the code. Once code execution is complete, the conditional will be evaluated once more. If the conditional is still "TRUE", the code will execute again.

Remember that the "VerilUOC_Desktop" section in module 2 contains all the information you need about this tool. The setup time is the minimum amount of time before a rising clock edge occurs that a signal must arrive at the input of a flip-flop in order for the flip-flop to latch the data correctly. Likewise, the hold time is the minimum time a signal must remain stable after the rising clock edge occurs before it can be allowed to change.
