It is based on the principles of Boolean logic, which deals with binary variables and logical operations. Boolean algebra allows us to manipulate and simplify complex logic expressions using basic algebraic rules. It helps me to understand the way of designing in digital electronics.
Combinational circuits (II)
By combining different logic gates, complex functions and operations can be achieved. Combinational circuits are digital circuits where the output depends only on the current input values. These circuits do not have any memory elements and are used to perform specific functions, such as arithmetic operations or data encoding/decoding. Combinational circuits are designed using logic gates and Boolean algebra.
Special Gates
The output of Ex-NOR gate is ‘1’, when even number of ones present at the inputs. Hence, the output of Ex-NOR gate is also called as an even function. Ex-OR gate operation is similar to that of OR gate, except for few combination(s) of inputs. The output of Ex-OR gate is ‘1’, when odd number of ones present at the inputs. Hence, the output of Ex-OR gate is also called as an odd function. That means, the output of an OR gate will be ‘1’, when at least one of those inputs is ‘1’.
Written Boolean Logic
Logic gates are electronic devices that perform logical operations on binary inputs to produce binary outputs. There are several types of logic gates, including AND, OR, NOT, XOR, NAND, and NOR gates. Each gate has its own truth table, which defines the output based on the input combinations. Digital logic allows us to process and manipulate binary information, which is the basis of all digital systems. By using logic gates and Boolean algebra, we can perform logical operations on binary inputs to produce desired outputs. This ability to perform logical operations forms the building blocks of digital circuits and enables the creation of complex systems.
NOT gate
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’.
Combinational Circuits
For example, an AND gate produces a high output only when both of its inputs are high. On the other hand, an OR gate produces a high output if any of its inputs are high. By combining different logic gates, we can create complex circuits that perform various logical operations. Truth tables are used to represent the output of a logic gate or circuit for all possible combinations of inputs. They provide a systematic way of determining the output based on the input values.
This repeats over and over, until the conditional evaluates to "FALSE" or a break statement is encountered. It is generally quite important that the values compared be of the same data type; unexpected things can happen if you compare a "byte" and an "int", for example. Now, let us discuss about the Logic gates come under each category one by one.

Combinational circuits are designed using Boolean algebra and truth tables to determine the output based on the input combinations. The NAND gate symbols and their meanings refer to the various graphical representations used to depict NAND gates in digital logic circuits. A NAND gate is a logic gate that performs the Boolean operation of the logical “AND” followed by negation. The symbols used for NAND gates are designed to convey specific meanings.

NOR gate is a digital circuit that has two or more inputs and produces an output, which is the inversion of logical OR of all those inputs. NAND gate is a digital circuit that has two or more inputs and produces an output, which is the inversion of logical AND of all those inputs. Logic gates are implemented using different types of electronic components, such as transistors, which act as switches.
Understanding digital logic makes complex decision making possible in programs. Digital, or boolean, logic is the fundamental concept underpinning all modern computer systems. Put simply, it's the system of rules that allow us to make extremely complicated decisions based on relatively simple "yes/no" questions.
Digital logic is essential for designing and implementing logic circuits. Logic gates, which are the basic building blocks of digital systems, are combined to create more complex circuits known as combinational and sequential circuits. Digital Logic Basics is the foundation of modern digital electronics. It involves the study of binary numbers, logic gates, and Boolean algebra, which are essential for understanding how digital systems work.
DLD V 2.0 ReleasedDigital Logic Design is a Software tool for designing and simulating digital circuits. It provides digital parts ranging from simple gates to Arithmetic Logic Unit. You may start your circuit from simple gates and flipflops and keep on converting them into ICs. These ICs, later on, may be incorporated into other circuits to built more complex circuits like CPU. You may even use SOP expressions to generate digital circuits in IC form. You can use this software to design Combinational, Synchronous and Asynchronous Sequential Circuits.
The UAB has a total of over 3,500 teaching and research staff, over 2,000 administrative staff and over 40,000 students. Now that we can create complex logical statements, let's look at the things we can do with the answers to those questions. A useful function of the T flip-flop is as a clock division circuit. If T is held high, the output will be the clock frequency divided by two. A chain of T flip-flops can thus be used to produce slower clocks from a device's master clock. The following figure shows the symbol of Ex-NOR gate, which is having two inputs A, B and one output, Y.
