If Transmitting a Digital Signal, Use a Manchester Code

question 56

Short Answer

If transmitting a digital signal, use a Manchester code. Because a Manchester code always has a signal transition in the middle of each bit, the receiver can anticipate this signal transition and read the incoming data stream with no errors. A Manchester-encoded digital signal is an example of a self-clocking signal.
