Communication trainers offers experiments for fundamental technical concepts in telecommunication. It enables students to acquire a clear experimental view and further, they will be familiar with the operative aspects of the work in the telecommunication laboratory.

Digital signal

Any type of data is transferred in analog signal. Any data is converted into electric form first and after that it is passed through communication channel. Analog communication uses a continuous signal which varies in amplitude, phase, or some other property with time in proportion to that of a variable. They digital signal consists of discrete values rather than continuous values. In digital communication physical transfer of data occurs in the form of digital bit stream i. In digital communication the digital transmission data can be broken into packets as discrete messages which is not allowed in analog communication.

Analog vs. Digital

A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on, at most, one of a finite number of values. Simple digital signals represent information in discrete bands of analog levels. All levels within a band of values represent the same information state. In most digital circuits , the signal can have two possible valid values; this is called a binary signal or logic signal. These correspond to the two values "zero" and "one" or "false" and "true" of the Boolean domain , so at any given time a binary signal represents one binary digit bit. Because of this discretization , relatively small changes to the analog signal levels do not leave the discrete envelope, and as a result are ignored by signal state sensing circuitry. As a result, digital signals have noise immunity ; electronic noise , provided it is not too great, will not affect digital circuits, whereas noise always degrades the operation of analog signals to some degree.


➢ There are two basic type of communication namely point to point and broadcast. The former take place over a link between a single transmitter and receiver.

 О да, конечно, - медленно проговорила женщина, готовая прийти на помощь потенциальному клиенту.  - Вам нужна сопровождающая. - Да-да.

 После вас, Сью, - сказал. ГЛАВА 41 В кладовке третьего этажа отеля Альфонсо XIII на полу без сознания лежала горничная. Человек в очках в железной оправе положил в карман ее халата связку ключей.

Прихожане могли понять нетерпение этого человека, стремившегося получить благословение, но ведь существуют строгие правила протокола: подходить к причастию нужно, выстроившись в две линии. Халохот продолжал двигаться. Расстояние между ним и Беккером быстро сокращалось.

Не открыв своего алгоритма, он доказал АНБ, что тот не поддается дешифровке. Стратмор протянул Сьюзан газетную вырезку. Это был перевод рекламного сообщения Никкей симбун, японского аналога Уолл-стрит джорнал, о том, что японский программист Энсей Танкадо открыл математическую формулу, с помощью которой можно создавать не поддающиеся взлому шифры. Формула называется Цифровая крепость, говорилось в заметке, и доступна для ознакомления в Интернете. Программист намеревался выставить ее на аукционе и отдать тому, кто больше всех заплатит.


The Two basic types of communication systems are. (i) Analog. (ii) Digital. In Analog Systems: Both the information and the carrier are analog signals. In Digital.
