Binary Encoder – Construction, Types & Applications

Schematic of 8 to 3 line encoder using OR gate

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 …

Sum Of Product (SOP) & Product Of Sum (POS)

Schematic Design of Sum Of Product (SOP)

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 …

Digital Flip-Flops – SR, D, JK and T Flip Flops

Symbol and Circuit of Basic SR Flip-Flop

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 …

Digital Logic NAND Gate – Universal Gate

Digital Logic NAND Gate Symbol and Boleen Expression

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 …

Exclusive-NOR (XNOR) Digital Logic Gate

LOGIC XNOR or Exclusive-NOR 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, …
