In
electronics, a
logic gate is an idealized or physical device implementing a
Boolean function; that is, it performs a
logical operation on one or more logical inputs, and produces a single logical output. Depending on the context, the term may refer to an
ideal logic gate, one that has for instance zero
rise time and unlimited
fan-out, or it may refer to a non-ideal physical device (see
Ideal and real op-amps for comparison).
