Encoder (digital)
An encoder (or “simple encoder”) in digital electronics is a one-hot to binary converter. That is, if there are 2 input lines, and at most only one of them will ever be high, the binary code of this ‘hot’ line is produced on the n -bit output lines. A binary encoder is the dual of a binary decoder.
If the input circuit can guarantee at most a single-active input, a simple encoder is a better choice than a priority encoder, since it requires less logic to implement. However, a simple encoder can generate an incorrect output when more than a single input is active, so a priority encoder is required in such cases.
