Coaxial Cable 13. The term "radio" does not solely cover devices such as radios. The forms of telecommunication can be through audio, video or text, or a mixture of all three. A feature-oriented description consists of a base de-scription and feature modules, each of which describes a separate feature. This placement in turn depends on the nature of the waveform that is being quantized. An example of data being processed may be a unique identifier stored in a cookie. In terms of the technology used, they can be classified as follows: Telephony: systems based on satellites and broadcasting towers that send the signal and the telephone equipment converts it into a voice that arrives clearly and with hardly any perceptible delay. 0000004568 00000 n 0000007008 00000 n As we know network use different software and hardware to transmit data via communication channels and that vary with the different medium so the telecommunication is responsible for converting and managing the speed of transmission independent to the platform. Telecommunication systems is emphasis of some of the essential components that transmit data from one end to another through an electronic medium and each component perform different task. (In data transmission this step is bypassed because the signals are already in digital form; most television, radio, and voice communication, however, use the analog system and must be digitized.) Lathi Probability, Random Variables and Stochastic processes by Peebles Fundamentals of Digital Communication by Proakis Communication Engineering Curriculum At the receiving end, the reconstituted signal is expanded to its original range of amplitudes.
