Characteristics of Digital Baseband Transmission

  • Jan W. M. Bergmans


Digital transmission systems usually transport information in a band of restricted width that is centered around some carrier frequency. The carrier frequency is typically large with respect to the bandwidth of the information-bearing signal, but in some cases (notably in certain voiceband data modems) it is of the same order of magnitude. The distinguishing feature of baseband transmission is that the carrier frequency is zero, i.e. that data is transmitted in a band around DC. As exemplified in Chapter 2, this approach is well-suited for channels that only pass frequencies near DC, such as wire pairs and digital recording channels.
