Description
Technical Field
[0001] The utility model belongs to the technical field of scientific educational experiments, in particular to a telegraph machine for educational experiments. Background Art
[0002] Telegraph, a device used to send and receive telegrams. Telegraph is a type of communication service. It was invented in the early 19th century and was the earliest method of using electricity for communication. The telegraph greatly accelerated the circulation of messages and was one of the important inventions of industrial society. The working principle of the telegraph: using electric current (wired) or electromagnetic waves (wireless) as a carrier, through coding and corresponding electrical processing technology to achieve a communication method of long-distance transmission and exchange of information. It includes a transmitter and a receiver. The transmitter emits electric currents of different frequencies and wavelengths, forming sparse and dense plane "waves" of different frequencies and wavelengths in all directions of space. When this "wave" hits the radio receiving antenna, it drives the free electrons on its surface to rotate around the antenna according to the frequency and wavelength of the "wave" to form an alternating current. This weak current is amplified and becomes the receiving information of the receiver;
