Explain the concept of Digital-to-Digital encoding. Sketch the Differential Manchester coding and RƵ encoding of the following bit stream:
Digital-to-digital encoding is a fundamental process in data communication and computer networks, where digital data (binary 0s and 1s) are transformed into a format suitable for transmission over a physical medium. This encoding ensures that the transmitted signal can be accurately interpreted at the receiving end, despite potential noise and distortion during transmission.
