Logic gates are elementary building blocks of digital circuits that have inputs and outputs representing binary digits 0 and 1. There are several basic types of logic gates including AND, OR, NOT, XOR, NAND, NOR, and XNOR gates. Each gate functions according to specific rules - for example, an AND gate only outputs 1 if all its inputs are 1, while a NAND gate produces the opposite output of an AND gate. Logic gates are used in various electronic devices and circuits.Logic gates

Digital systems use logic gates like AND, OR, NOT, NAND, NOR, EXOR and EXNOR. The AND gate outputs 1 only if all inputs are 1. The OR gate outputs 1 if one or more inputs are 1. The NOT gate inverts the input, outputting 1 for a 0 input and vice versa. NAND and NOR gates are composed of an AND/OR gate followed by a NOT. EXOR outputs 1 if either but not both inputs are 1, while EXNOR does the opposite. Truth tables define all possible input/output combinations for each gate.Logic gates

NAND and NOR gates are universal logic gates because they can be used to implement all other basic logic gates. Specifically:
- A NAND gate can act as an inverter, and two or three NAND gates can be configured to act as an AND gate or OR gate respectively.
- Similarly, a NOR gate can act as an inverter, and two or three NOR gates can be arranged to perform the logic of an OR gate or AND gate.
This property means that only NAND or NOR gates are needed to build any digital circuit, making them universal fundamental building blocks for logic. multiplexers and demultiplexers

Logic gates are elementary building blocks of digital circuits that have inputs and outputs representing binary digits 0 and 1. There are several basic types of logic gates including AND, OR, NOT, XOR, NAND, NOR, and XNOR gates. Each gate functions according to specific rules - for example, an AND gate only outputs 1 if all its inputs are 1, while a NAND gate produces the opposite output of an AND gate. Logic gates are used in various electronic devices and circuits.Electronics: Logic Gates

Logic gates are electronic components that perform logical operations based on binary inputs, producing a single output. Various types of gates such as NOT, AND, and OR manipulate these inputs according to specific rules, detailed in truth tables and Boolean algebra. They are widely used in applications like control systems, where they function as automatic switches to manage outputs based on input signals.Logic gates and Boolean Algebra_VSG

BLUF:
The Texas outbreak has slowed down, but sporadic cases continue to emerge in Kansas, Oklahoma, and New Mexico.
Elsewhere in the US, we continue to see signs of acceleration due to outbreaks outside the Southwest (North Dakota, Montana, and Colorado) and travel-related cases. Measles exposures due to travel are expected to pose a significant challenge throughout the summer.

Here is the latest update:
CURRENT CASE COUNT: 919
Texas: 744 (+2) (55% of cases are in Gaines County).
New Mexico: 81 (83% of cases are from Lea County).
Oklahoma: 20 (+2)

This presentation has been made keeping in mind the students of undergraduate and postgraduate level. In this slide try to present the brief history of Chaulukyas of Gujrat up to Kumarpala To keep the facts in a natural form and to display the material in more detail, the help of various books, websites and online medium has been taken. Whatever medium the material or facts have been taken from, an attempt has been made by the presenter to give their reference at the end.
Chaulukya or Solanki was one of the Rajputs born from Agnikul. In the Vadnagar inscription, the origin of this dynasty is told from Brahma's Chauluk or Kamandalu. They ruled in Gujarat from the latter half of the tenth century to the beginning of the thirteenth century. Their capital was in Anahilwad. It is not certain whether it had any relation with the Chalukya dynasty of the south or not. It is worth mentioning that the name of the dynasty of the south was 'Chaluky' while the dynasty of Gujarat has been called 'Chaulukya'. The rulers of this dynasty were the supporters and patrons of Jainism.YSPH VMOC Special Report - Measles Outbreak Southwest US 6-14-2025.pptx

Logic gates
- 1. Prepared by Gayithri Ashwathreddy Assitant professor, SKC
- 2. AGENDA Introduction to logic Gates Types of Logic gates Universal gates Realization of basic Gates with Universal gates. Implementation of logic gates with Boolean expressions
- 3. INTRODUCTION A Digital Logic Gate is an electronic circuit which makes logical decisions based on the combination of digital signals present on its inputs. Logic gates are the basic building blocks of any digital system. It is an electronic circuit having one or more than one input and only one output. The relationship between the input and the output is based on a certain logic.
- 4. TYPES OF GATES Basic gates Derived Gates
- 5. AND GATE It has two or more input signal but only one output signal If all the input signal is high(1),then the output signal is 1(high) otherwise it is zero(0)
- 6. OR GATE It has two or more input signal but only one output signal If any of the input signal is high(1),then the output signal is 1(high)
- 7. NOT GATE A NOT gate has only one input and one output. The output state is always the opposite of the input state. The output is sometimes called the complement (opposite) of the input. NOT gate is also called as INVERTER Gate, Because the output is not same as the input
- 8. BUFFER GATE A Buffer gate has only one input and one output. The output state is remains as of the input state.
- 9. NAND GATE A NAND gate has two or more input signal but only one output signal. The NAND gate is a complemented of AND gate. The output of NAND gate will be 0 only when all inputs are 1 and output will be 0 if any input represents a 0 NAND is short form of NOT AND
- 10. NOR GATE NOR gate has two or more input signal but only one output signal. The NOR gate is a complemented of OR gate. The output of NOR gate will be 1 only when all inputs are 0and output will be 0 if any input represents 1. NOR is short form of NOT-OR
- 11. EXCLUSIVE OR(XOR) GATE An exclusive-OR has two or more input signal but only one output signal. Exclusive-OR gate is different form of OR gate. XOR gate produces output 1 for only those input combinations that have odd number of 1s. The output is 0 if there are even number of 1s in the input. The output is 1 if there are odd number of 1s in the input.
- 12. XNOR GATE The XNOR gate is complement of XOR gate. The output of XNOR is 1 only when the logic values of both X and Y is same i.e. either both are equal to 1 or both are 0. Its output is 0 when its inputs are different.
- 13. UNIVERSAL GATES Universal gates are gates which can be used to implement all other gates. This is useful as manufacturers only need to produce 1 type of universal gate to be able to use all other gates. The universal gates are NOR and NAND.
