OR and AND using transistors 1. These gates are related to Boolean Algebra. If both inputs are false 0 or both are true 1a false output 0 results. A similar result can be achieved using eight NAND gates. This makes it practically useful as a parity generator or a modulo-2 adder. Its behavior is summarized in the truth table shown on the right.
They are essentially a single-valued function of time. Note that this setup can only cross Boolean digital signals, and not analog signals, so would of limited use in an amplifier or other analog circuit.
Since the trailing sum bit in this output is achieved with XOR, the preceding carry bit is calculated with an AND gate. Using a preset as a variable resistor; verify the varying current using a multimeter. If a logic gate were to accept three or more inputs and produce a true output if exactly one of those inputs were true, then it would in effect be a one-hot detector and indeed this is the case for only two inputs.
It acts as an open circuit when it is reversed biased, i. What is a transistor? If either of the inputs are high, the corresponding N-channel MOSFET is turned on and the output is pulled low; otherwise the output is pulled high through the pull-up resistor.
Realizing the truth table of NOT gate and analyzing the path of the current in two cases; low and high inputs. Multiplexers, decoders, state machines, and other sophisticated digital devices all rely on the basic inverter. Diode as a switch; its functioning in forward bias and reverse bias modes; verifying biasing condition using a multimeter.

Which of the region regions represents I.
There are two types of signals: However, it is rarely implemented this way in practice. This unique property of diode is employed in the design of logic gates and the circuits.The main aim of this project is to derive all the gates and understand their functioning from the three basic gates.
Logic gates are the building blocks of digital technology. It is a mechanical, optical, or electronic system that performs a logical operation on an input signal.
Truth tables are used to help, show the function of a logic gate.

A mini project with logic gates won't be that simple. for making an impressive mini project using logic gates will have to build sequential circuits like counter, registers, flip flops.
The OR gate is a digital logic gate that implements logical disjunction - it behaves according to the truth table to the right. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1).Download
