What's the difference between NRZ, Manchester (Phase Encoding or PE), NRZI, and RZ, coding. What's the difference between unipolar and bipolar signaling. How clocking is determined to extract data ...

Digital transmission is the sending of information over physical communication media in the form of digital signals. Analog signals must therefore be digitized first before being transmitted. The ...

Non-return-to-zero (NRZ), non-return-to-zero-inverted (NRZI), return-to-zero (RZ), and Manchester are popular serial encoding mechanisms. Each has different characteristics that make it useful in ...
