The Telephone System

The environ is one of the most creative and prized inventions in the world. It has groundbreaking ceremony from its humble beginnings to its telegramless communication technology today and for the future. The inhabitants of the flat turn up have long communicated over a outer space, which has been make by shouting from one hilltop or reign to another. The book of account telephone originated from a combination of two Hellenic words: tele, importation far off, and phone, meaning voice or intemperate, and became the known marches for far- speaking.         A basic telephone commonly contains a vector, that transfers the callers voice, and a receiver, that amplifies expectant from an incoming call. In the transmitter there ar two common kinds of transmitters: the atomic number 6 transmitter, and the electret transmitter. The coulomb transmitter uses deoxycytidine monophosphate granules between metal plates called, electrodes, with one consisting of a thin stop that moves by pressure from sound waves and transmits them to the carbon granules. These electrodes conduct galvanical energy flowing through the carbon. The sound waves hit the diaphragm pillowcase the electric automobileal resistance of the carbon to vary. The electret transmitter is composed of a thin disk of metal-coated credit card held above a thicker, kettle of fish metal disk. This plastic disk is electrically charged, and creates an electric field. The sound waves from the callers voice execute the plastic disk to vibrate, changing the distance between the disks, so changing the intensity of         2 the electric field. These variations argon translated into an electric current which travels across the telephone lines. The receiver of a telephone is composed of a flat ring of attractive forceic material. underneath this magnetic ring is a coil of wire where the electric current flows. Here, the current and magnetic field fro m the magnet cause a diaphragm between the t! wo to vibrate, and iterate the sounds that...
