Diode logic was used extensively in the construction of early computers, where semiconductor diodes could replace bulky and costly active vacuum tube elements. The most common use for diode logic is in diode—transistor logic DTL integrated circuits that, in addition to diodes, include inverter logic to provide a NOT function and signal restoration.

In this tutorial, we will have a brief introduction to Logic Gates. Logic gates are the heart of digital electronics. A gate is an electronic device which is used to compute a function on a two valued signal. Logic gates are the basic building block of digital circuits.

## OR and AND logic gates made with diodes

A logic gate is an idealized or physical device implementing a Boolean function, that is, it performs a logical operation on one or more logic inputs and produces a single logic output. They are primarily implemented using diodes or transistors acting as electronic switches.

Digital logic gates process digital signals as input and produce a digital signal as output. Logic gates are an essential part of digital circuitry and are implemented using transistors or diodes. The logic for each gate is often represented in a truth table. As the name implies, inverter will invert the number entered. If you enter 0, you will get a 1 on its output, and if you enter a 1, you will get a 0 on its output. AND gate always has a false output unless both inputs are true.

What Logic gate circuit was constructed? Diode OR-gate circuit After constructing the circuit, record its observed characteristics by filling up the truth table below.

Connect the negative side of the diodes A and B to the S1 and S2 terminal of the logic trainer. Connect the output Y to the L1 of the trainer. Diode AND-gate circuit After constructing the circuit, record its observed characteristics by filling up the truth table below. Connect the base terminal of transistor A to S1 terminal of the logic trainer. Transistor Inverter Circuit. After constructing the circuit, record its observed characteristics by filling up the truth table below.

Connect the base terminal of transistors A and B to the S1 and S2 terminal of the logic trainer. Transistor OR-gate circuit After constructing the circuit, record its observed characteristics by filling up the truth table below. Connect the base terminal of the transistors A and B to the S1 and S2 terminal of the logic trainer. Transistor AND-gate circuit After constructing the circuit, record its observed characteristics by filling up the truth table below.

Conducting this experiment on diode and transistor logic gates, the group was able to observe the characteristics and behavior of the circuits found in figures 1.

The gathered data about the said circuits were recorded on the truth tables found every after each procedure. This is the very reason why the circuit on Fig. When either of the terminals A or B was supplied, still there was no observable output on the terminal Y;. In order to have an output on this type of circuit, at least one terminal must be supplied.

## Introduction to Logic Gates

A digital system is basically a binary world. One where the language is restricted to 1s and 0s. Therefore, to make the best of these 1s and Os, logic gates form the foundation to build a digital system that we know today. Hence, if you are keen on understanding digital electronics, you must be clear with the basic boolean logic. This article is all about logic gates and their types. It aims to be a stepping stone for all the digital electronics enthusiasts who are embarking on their learning journey.

Activity 1. Logic gates are the basic building blocks of any digital system. Due to this reason logic gates can also be considered as electronic circuits. View Lab Report 1 - 1 Logic Gates. The output BJT switches between its cut-off and saturation regions to create logic 1 and 0, respectively.

### Electronic Logic Circuits

Edition: 9. Field effect transistors FETs are three-terminal devices in which the flow of charge carriers either electrons or holes through a semiconductor channel is controlled using an electric field. As we know that a transistor is a combination of two diodes, we have two junctions here. The operation of npn and pnp transistors are same if the roles played by the electrons and holes are interchanged.

Его руки внезапно снова потянулись к ней в отчаянном порыве. Он целовал ее щеки. - Прости меня, - умолял. Сьюзан пыталась отстраниться, но он не отпускал. ТРАНСТЕКСТ задрожал, как ракета перед стартом. Шифровалка содрогалась.

Если Дэвид успеет найти кольцо, мы спасем банк данных. Стратмор ничего не. - Позвоните в банк данных! - приказала Сьюзан.  - Предупредите их о вирусе. Вы заместитель директора АНБ и обязаны победить.

Когда улица сделала поворот, Беккер вдруг увидел прямо перед собой собор и вздымающуюся ввысь Гиральду. Звон колоколов оглушал, эхо многократно отражалось от высоких стен, окружающих площадь. Людские потоки из разных улиц сливались в одну черную реку, устремленную к распахнутым дверям Севильского собора. Беккер попробовал выбраться и свернуть на улицу Матеуса-Гаго, но понял, что находится в плену людского потока. Идти приходилось плечо к плечу, носок в пятку.

Беккер оказался зажат между двумя полными женщинами с закрытыми глазами, предоставившими толпе нести их в собор. Они беззвучно молились, перебирая пальцами четки.

- Но будем надеяться, что он этого не узнает. ГЛАВА 76 У подъезда севильского аэропорта стояло такси с работающим на холостом ходу двигателем и включенным счетчиком. Пассажир в очках в тонкой металлической оправе, вглядевшись сквозь стеклянную стену аэровокзала, понял, что прибыл вовремя. Он увидел светловолосую девушку, помогающую Дэвиду Беккеру найти стул и сесть.

Еще раз убедившись, что Сьюзан и коммандер поглощены беседой, Хейл аккуратно нажал пять клавиш на клавиатуре ее компьютера, и через секунду монитор вернулся к жизни.
