NOR and NAND Implementation – Two Level & Multilevel Introduction to NOR Gate & Its Implementation NOR gate is a universal gate which can implement any kind of Boolean logic function. NOR gate is commercially used because it allows the access to wired logic,which is a logic function formed by connecting the outputs of NOR gates. Wired logic does not …

Two-Level Logic Implementation – Implementation of Combinational Circuits Introduction Two level logic means that the logic design uses maximum two logic gates between input and output. This does not mean that the whole design will contain only two logic gates but the single path from input to output may contain no more than two logic gates. For two-level logic implementation, …

Digital Binary Encoder – Types & Construction What is Binary Encoder? A combinational circuit capable of converting “2n” input signals into “n” signals (such as BCD (Binary Coded Decimal) Binary etc) is called binary encoder also known as digital encoder.. Its operation is exactly opposite of Binary Decoder. In simple words, Binary Encoder used to encode a Binary Codes. It …

Digital Binary Adder & Subtractor What is Binary Adder ? A digital binary adder is a digital device that adds two binary numbers and gives its sum in binary format. The two numbers to be added are known as “Augand” and “Addend”. The first number in addition is occasionally referred as “Augand”. Digital adders are mostly used in computer’s ALU …

Product Of Sum (POS) & Sum Of Product (SOP) Sum Of Product (SOP) Sum of Product is the abbreviated form of SOP. Sum of product form is a form of expression in Boolean algebra in which different product terms of inputs are being summed together. This product is not arithmetical multiply but it is Boolean logical AND and the Sum …

Karnaugh Maps (K-Map), 1-6 Variables Simplification & Examples What is Karnaugh Map (K-Map)? Karnaugh map or K-map is a map of a function used in a technique used for minimization or simplification of a Boolean expression. It results in less number of logic gates and inputs to be used during the fabrication. Booleans expression can be simplified using Boolean algebraic …

Digital Flip-Flops – Types & Operation of Flip-Flops What is Flip-Flop? Digital flip-flops are memory devices used for storing binary data in sequential logic circuits. Latches are level sensitive and Flip-flops are edge sensitive. It means that the latch’s output change with a change in input levels and the flip-flop’s output only change when there is an edge of controlling …

Universal Digital Logic NAND Gate What is Logic NAND Gate? NAND Gate is a digital logic gate (Also known as Universal gate) produces logic LOW State “0” only and only when there is HIGH State “1” at all of the inputs. NAND gate is opposite /Invert of AND gate, in other words, if we connect NOT gate to the output …

Universal Digital Logic NOR Gate What is Logic Nor Gate NOR Gate is a digital logic gate (Also known as Universal gate) which gives output “1” only and only when all of its inputs are logic LOW state “0”. NOR gate is invert of OR Gate. In other words, if we connect NOT gate to the output of OR gate …

Exclusive-NOR Gate – Digital Logic XNOR Gate What is Logic XNOR or Exclusive-NOR Gate? XNOR gate also known as Exclusive-NOR or Exclusive-Negative OR gate is “A logic gate which produces High state “1” only when there is an even number of High state “1” inputs”. For 2-input gate, it can be interpreted as when both of the inputs are same, …
