WebJun 21, 2013 · If, for some reason, your input values are not in [0,1], then a bitwise OR will give you an answer that may also not be in [0,1]. Logical OR is guaranteed to give you 0 or 1. For this reason, you should prefer logical OR. Your intent is (presumably) to manipulate logical values, so using a non-logical operator is illogical. * WebJun 17, 2014 · The 1-bit signal is the selector, and the inputs are 3-bit signals.
