46Delay encoding — In telecommunications, delay encoding is the encoding of binary data to form a two level signal such that (a) a 0 causes no change of signal level unless it is followed by another 0 in which case a transition to the other level takes place at the …
47Differential Manchester encoding — Differential Manchester encoding, also called biphase mark code (BMC) or FM1, is a line code in which data and clock signals are combined to form a single 2 level self synchronizing data stream. It is a differential encoding, using the presence… …
