Convolve vs. convolute - English Language Usage Stack Exchange Convolved is a verb (both transitive and intransitive) As such, while you might say that "signal A is convolved with signal B", to say that "signal A is convoluted with signal B" would be butchery of the English language (And using convoluted as an adjective isn't terribly useful, unless you wanted to complain about the convoluted process )
