Communications systems, whether they are telephone, landline, or radio, cannot directly transport digital information without some distortion of the signal. This book is the only title. Chapter 1 Data Communications: Emergence Modems and Multiplexers. Multiplexer Innovation: American Data Systems The same dynamics that were driving the potential buying demand for modems were having a more immediate impact on multiplexers, the second great product of data communications. A multiplexer is a device that takes multiple analog signals and forwards the selected input into a single line. These devices are used to increase the amount of data that can be transmitted over a network. A network multiplexer is used with a variety of signal types like digital, video, analog, and optical.
Abstract. Long-distance data communication over analog telephone lines requires a device called a MOdulator-DEModulator or MODEM to convert the digital signals into analog signals with frequencies within the bandwidth of the telephone eduevazquez.com: John R. Freer. While many businesses rely heavily on Internet-based communication, computer modems still certainly have their place in many companies. With a fax modem, for example, your computer can send or receive data like a fax over phone or cable lines rather than slow down the speeds.
