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.

Polar NRZ-L, NRZ-I, RZ schemes

Polar NRZ-L, NRZ-I, RZ schemes. The voltages are on the both sides of the time axis NRZ-L (Non Return to Zero-Level): The level of the voltage determines the value of the bit NRZ-I (Non Return to Zero-Invert): If the bit is 0 there is no change; if the bit is 1 there is a change
