These devices are large and heavy machines, which have a keyboard and a printer, which was responsible for translating the electrical signals that were sent to you in printed characters. It was created thanks to the advances of the telegraphic techniques , and was in the year 1910 when the first commercially teletype, which was made by the company Morkrum was installed.

The teletype needed electrical current from 60 to 100 volts , so that the operation of it was of good quality. Because thanks to the electrical signals that result in positive and negative combinations, could get the characters were going to Print.

What it is and what are the tickers? How does it work ?, advantages and disadvantages

It is worth noting that the creator of these codes was the French Émile Baudot, who developed it in 1874. In order to communicate with each other, with others. The first artifact was only 5 keys , which provided a 5-bit code and these signals are expressed as points.

As time passed, the teletype was evolving. Year 1,901 was modified the code by Donald Murray and thus the teletype keyboard was like a typewriter , signs incorporating this way the keyboard. This, he came to reach 400 signs per second.

Note that the teletypes were used for postal service and the same could transmit messages . This advance was extended to global level after the Second World War, as it allowed them to send more than 60 words per minute in each message.

This reception apparatus work in two ways, the first is that the keyboard could act so emitter, which is responsible for decoding signals points and then the message is printed.

The second form of operation was that could act receptor , since it was printed by perforations in a sheet of paper electrical pulses received.

It is noteworthy that these artifacts counted several disadvantages among which we have communication. They were affected by a distortion in telegraph lines called “biaise” that alter the length of the transmitted pulse, but thanks to the AFSK modulation is achieved minimize this problem.

The technology of the century XX

This technological breakthrough was aimed transmit data in the twentieth century, which was responsible for sending messages and receive typed so by dots, it was a means of simple communication.

More than 200,000 tickers were sold for the year 1954 and today these electrical devices for people with hearing disabilities still use, in order to write down the telephone communications they have.

This device is very similar to a typewriter , since it has a keyboard. As time evolved was introduced signs, so it became an alphanumeric keyboard. All this with the purpose of writing messages and send and became the highest rise of the twentieth century communication.

Advance Technological

This breakthrough technology was very important at the time because it had speed , confidentiality, low cost, served as system data , counted accurately, for this reason, its impulse spans 70 years. Thereby transforming the system and cablegram mecanográfico the best device to communicate, it was a wonderful device.

The last message cable that the company issued was in 1996. important to highlight that thanks to these technological impulses, it evolved over the years until today, and thanks to this advance in the twentieth century could be refined to eventually become an ideal tool for people with hearing disabilities.

Finally, we hope this article has helped him help. However we like to know your opinión¿Conoce other uses and functionality of the teletype? Leave your answer in the comments.
