Logic gates are the basic building blocks of digital circuits and perform logical operations. The main logic gates are AND, OR, and NOT. An AND gate outputs 1 only if all its inputs are 1. An OR gate outputs 1 if any of its inputs are 1. A NOT gate inverts its single input. Logic gates are constructed from diodes, transistors, and resistors on a silicon chip and their inputs and outputs represent either 1 or 0, true or false. Combination gates like NAND and NOR are derived from basic logic gates and their truth tables define the output for all possible input combinations.

Presentation On Logic Gate
This presentation introduces logic gates. It defines a logic gate as a building block of digital circuits that takes two or more inputs and outputs one value based on Boolean algebra. Common logic gates are then described, including AND, OR, and NOT gates. NAND and NOR gates are universal gates that can be used to represent all other logic functions. Exclusive gates like XOR and XNOR are also discussed. Finally, compound gates are defined as combinations of basic logic gates to form more complex functions.
Boolean algebra And Logic Gates
1. Boolean algebra is a mathematical system used to specify and transform logic functions. It uses binary variables that take on values of 1 or 0 and logical operators like AND, OR, and NOT.
2. Logic gates implement logic functions physically using electronic components. Common gates are AND, OR, and NOT. Gates have a small but nonzero delay between input change and output change.
3. Boolean expressions can be represented using truth tables, logic diagrams, or algebraic expressions. Standard forms include sum-of-minterms and product-of-maxterms forms.
Logic gates
This document discusses logic gates and their truth tables. It begins by introducing basic logic gates like AND, OR, NOT, NAND, NOR, XOR and XNOR. It then provides details on each gate, including their symbols, truth tables and how they can be represented electrically. The document also discusses how gates can be connected together and how multi-input gates like 3-input and 4-input AND and OR gates work based on the same principles as 2-input gates. Finally, it notes that the output of one gate can be used as input to another, allowing logic circuits to be built from connected gates.
Sequential circuits
The document discusses sequential circuits and different types of flip flops and counters. It describes how sequential circuits have memory and their output depends on current and past inputs. There are two main types of sequential circuits - asynchronous which can change state at any time and synchronous which use a clock signal to control when the output can change state. Common types of flip flops described include SR, JK, D and T flip flops. Counters can be asynchronous with the clock signal rippling through or synchronous where all flip flops share the same clock.

Boolean algebra can be used to simplify logical expressions and save gates in digital circuit design.
Multiplexers
A multiplexer is a device that selects one of several analog or digital input signals and forwards the selected input into a single line. It has multiple data inputs, a single output, and select lines that determine which input is directed to the output. A demultiplexer performs the opposite function, taking a single input and distributing it to one of multiple outputs based on the select lines. Multiplexers and demultiplexers come in various configurations depending on the number of inputs and outputs, such as 2:1, 4:1, 16:1 or 32:1. They are basic building blocks used in digital systems and communication networks to efficiently route signals.
Sr Latch or Flip Flop
The document describes the workings of an SR latch circuit. An SR latch consists of two cross-coupled NOR or NAND gates with inputs named S (Set) and R (Reset). The circuit can be in one of two states: the set state where output Q=1 and Q'=0, or the reset state where Q=0 and Q'=1. When S=1 and R=0, the circuit enters the set state by forcing Q to 1 and Q' to 0. When R=1 and S=0, the circuit enters the reset state with Q=0 and Q'=1. Once set or reset, the state will be maintained even if the input changing it toggles again.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Basic Logic gates
- 1. LOGIC GATES
- 2. WHAT ARE LOGIC GATES? The Logic Gate is the simplest integrated circuit (IC). They are called logic gates because the circuits act like gates in a fence. The gate is either open or closed depending on the conditions set.
- 3. THE BASIC LOGIC GATES AND : acts in the same way as two switches are placed in series. X equals A and B X= A.B OR: operates like a circuit with two switches placed in parallel. X equals A or B X= A+B NOT: acts in the same way as a transistor. It is an INVERTER. A with a bar is read as Not A
- 4. LOGIC GATES consist of diodes, transistors and resistors assembled in a silicon chip.
- 5. LOGIC GATES SYMBOL AND TRUTH TABLES At any given time, every terminal may have an input or output of 1(high) or 0 (low). In most logic gates, the low state is approx. 0 volt, while the high state is 5 volts or 6 volts in some.
- 6. Take Note: The inputs and outputs of logic gates are either 1 or 0 which stands for Yes or No; True or False; or high or low voltages respectively.
- 7. OTHER TYPES OF LOGIC GATES These are the simplest combination gates derived from the basic logic gates. NAND gate is a combination of AND and NOT gate. NOR gate is an OR and NOT gate combination.
- 8. OTHER TYPES OF LOGIC GATES TRUTH TABLES
- 9. TRY THIS! A system of AND gates with 5 inputs A B C D E What is the final output in X if A = 1 and B = 0, C = 0, D = 1 and E = 1 ? X
- 10. TRY THIS! A = 1 and B = 0, What is the final output at X? X
- 11. A system of combination of gates. A B C D Determine the output in X if A and B are both 1 and C and D are both 0? X
