https://doi.org/10.1007/978-3-662-33136-1If a device transmits a continuous stream of bit patterns it should arrive without distortion at the receiver. This is also true of the retrieval of data from a storage medium. The yardstick par excellence for the quality of transmission or storage is the so-called bit error probability.

Zwei Fragen zur Definition eines Begriffs,Digital signals at the output of an encoder are a sequence of numbers in the form of a bit stream. In order to be able to transmit such bit patterns via a physical medium (cable or space) they have to be converted into a modulated, continuous-time signal, which is, in the final analysis, analog.

,The concept: methods — content — objectives,Microelectronics is already the key industry (see Illustration 9). In the view of experts in this field it has changed our lives more than any other technology and will continue to do so. It is probably impossible for us to imagine the social, political and economic impact of this technology.
