Bus Transceiver
https://www.electronics-lab.com/article/bus-transceiver/
Bus Transceiver A Transceiver is a device allowing a bidirectional interface between buses for either digital or analog signal communication and has input & output control capability. It uses back-to-back Tri-state buffers for the communication of multiple devices over a common data bus. Contrary to a Digital Buffer, a Tri-state Buffer allows bidirectional communication and […]
Product of Sum
https://www.electronics-lab.com/article/product-of-sum/
Product of Sum In the Sum of Product article, we discussed that the Sum of Product (SOP) expression is equivalent to the logical AND-OR function. Likewise, a Product of Sum (POS) expression is equivalent to the logical OR-AND function which means it outputs the Product (AND) of two or more Sums (OR). The Product of […]
Switching Theory
https://www.electronics-lab.com/article/switching-theory/
Switching Theory The switching theory uses switches in order to understand the operation and functioning of digital logic gates and circuits. The switching theory helps in developing better theoretical knowledge and concepts of digital logic circuits involving logical inputs producing a specific relational logical output. As it has already been discussed that Boolean data type […]
Boolean Algebra Examples
https://www.electronics-lab.com/article/boolean-algebra-examples/
Boolean Algebra Examples In the previous articles, it has been shown that the digital logic gate and digital circuit can be represented by a Boolean expression and a truth table. A Boolean expression consists of a number of variables representing inputs and an output which is usually represented by a “Q”. The inputs and outputs […]
Logic NOT Function
https://www.electronics-lab.com/article/logic-not-function/
Logic NOT Function The logic NOT function’s output state is NOT the same as its input state. The logic NOT function performs the inversion function on its input and outputs complement of the input. The logic NOT function output is false when its input is true, and true when its input is false. It is […]
Digital Buffer
https://www.electronics-lab.com/article/digital-buffer/
Digital Buffer The digital buffers are used in digital circuits for the amplification of digital signals in order to drive high current loads. Besides current amplification, the digital buffers provide isolation between input and output circuits where output is connected to some high-power load such as a relay, lamp or solenoid, etc. The digital device […]
Logic NOR Gate
https://www.electronics-lab.com/article/logic-nor-gate/
Logical NOR Gate The logic NOR gate is the reverse or complement form of the logic OR gate which was discussed in the previous article. Similar to the logic NAND gate, it is a series combination of logic OR gate and an inverter thus forming a logic NOR gate. The logic NOR gate equivalent is […]
Logic NAND Gate
https://www.electronics-lab.com/article/logic-nand-gate/
Logic NAND Gate The NAND gate is a logic AND gate with an inverted output. It is a reverse or complement of a AND gate discussed previously. The logic AND gate output logic “HIGH” when all of its inputs are at logic level “HIGH”. Contrary to this, the logic NAND gate outputs logic “LOW” when […]
Logic OR Gate
https://www.electronics-lab.com/article/logic-or-gate/
Logic OR Gate The logic OR gate gives an output of logic “HIGH” when any of its inputs goes to the “HIGH” logic level. The logic OR gate can have multiple inputs and only one output. The logic OR gate gives an output of logic “LOW” only when all of its inputs are at logic […]
Logic AND Gate
https://www.electronics-lab.com/article/logic-and-gate/
Logic AND Gate We know from the Digital Logic Gates Introduction that a digital circuit at its input and output can have only two – states i.e. either “HIGH” or “LOW”. The logic “HIGH” and “LOW” are also termed as “1” and “0” logic, respectively. The voltage level at the input or output is the determinant […]
