DIGITAL-TO-DIGITAL CONVERSION

DIGITAL-TO-DIGITAL CONVERSION. In this section, we see how we can represent digital data by using digital signals. The conversion involves three techniques: line coding , block coding , and scrambling . Line coding is always needed; block coding and scrambling may or may not be needed.

Transmitting digital signals

Transmitting digital signals. How do we encode digital signals for transmission? How can we interpret those signals?. Baseband transmission. S ignal is sent without conversion to an analog signal. Requires a transmission channel with bandwidth that starts at 0Hz (a low-pass channel).
