Test a Diode by Analog & Digital Multimeter Troubleshooting Electronic Devices & Components Troubleshooting in electronic and electrical engineering is an important part and one must know the basic skills and knowledge about the components to design and troubleshoot a circuit. It is advisable to test component before assembling and placing in a circuit. Sometimes, we get unexpected results and …

Types of Digital Latches, Construction & Applications What is Digital Latch? A sequential logic circuit or electronic device used for storing binary information is known as Latches. Latches are bi-stable multi-vibrator; it means that latches have 2 stable states, LOW and HIGH. It stores the information provided to it in binary form and does not need a constant input. The …

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 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 …

Digital Binary Decoder – Types & Construction What is Binary Decoder? A digital combinational circuit used for converting “n” bits of binary number into a combination of “2­n” or less unique and separate output lines is called digital decoder or binary decoder. In simple words, Binary Decoder used to decode a Binary Codes and it is the reverse of Binary …

Digital Demultiplexer (Demux) What is Digital Demultiplexer (Demux)? A digital device capable of forwarding its single input onto any one of the output lines is called Demultiplexer abbreviated for DEMUX. It is the reverse of Multiplexer. A Demultiplexer has a single input and multiple outputs. It has 2n output lines where “n” is the number of control signals. Each combination …

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, …
