Simple Logic Gates and Circuits: Logic gates are some of the basic building blocks of digital logic circuitry. In this Instructable we will talk about a few of the simplest of these devices, and see some of the fun things you can do with them. So what are logic gates? Logic g...

binational Logic Circuits are made up from basic logic NAND, NOR or NOT gates that are “combined” or connected together to produce more complicated switching circuits. These logic gates are the building blocks of combinational logic circuits. An example of a combinational circuit is a decoder, which converts the binary code data present at its input into a number of different output ...

An AND gate is a digital logic gate with two or more inputs and one output that performs logical conjunction. The output of an AND gate is true only when all of the inputs are true. If one or more of an AND gate's inputs are false, then the output of the AND gate is false. The truth table for an AND gate with two inputs appears to the right ...

circuits wherein logic gates employ diodes in the input stage and bipolar junction transistors at the output stage. The output BJT switches between its cut off and saturation regions to create logic 1 and 0, respectively. The logic level shift problem of DRL gates is not present in DTL and TTL gates so that gates may be connected in series ...

Below is a simple AND gate logic circuit designed for a dog. The dog’s owner is very concerned that when he is at work he can gain entrance to the kennel he has made. The kennel is situated outside. However, recently a cat has been entering the kennel and eating the dogs food.

AND Gate for Logic Circuit Applications: Logic gates are the fundamental building blocks of digital circuits; it's how computers record and transmit information! The most basic logic gates (like the AND gate) help you interpret two binary inputs to control a single output. Binary means...

LOGIC GATES (PRACTICE PROBLEMS) Key points and summary – First set of problems from Q. Nos. 1 to 9 are based on the logic gates like AND, OR, NOT, NAND & NOR etc. First four problems are basic in nature. Problems 3 & 4 are based on word statement. Problems 5 to 9 are on Universal gates. How the logic circuits can be designed using these gates?

Logic gates. Digital systems are said to be constructed by using logic gates. These gates are the AND, OR, NOT, NAND, NOR, EXOR and EXNOR gates. The basic operations are described below with the aid of truth tables. AND gate. The AND gate is an electronic circuit that gives a high output (1) only if all its inputs are high. A dot (.) is used to ...

In electronics a NOT gate is more commonly called an inverter. The circle on the symbol is called a bubble and is used in logic diagrams to indicate a logic negation between the external logic state and the internal logic state (1 to 0 or vice versa). On a circuit diagram it must be accompanied by a statement asserting that the positive logic convention or negative logic convention is being ...
