plural of polyphaser

A machine generating more than one pressure wave.

Having multiple coexisting phases / Having multiple successive peaks of activity

The condition of being polyphasic

(electrical) A group of alternating current circuits having two or more interrelated voltages, usually of equal amplitudes, phase differences, and periods, etc; if a neutral conductor exists, the voltages referenced to the neutral are equal in amplitude and phase; the most common version is that of 3-phase, equal in amplitude with phases 120 degrees apart.

plural of polyphase circuit
