phase shiftern.

Brit.

/ˈfeɪz ˌʃɪftə/, U.S.

/ˈfeɪz ˌʃɪftər/

Origin: Formed within English, by compounding. Etymons: phase n.², shifter n.

Etymology: < phase n.² + shifter n. Compare phase-shifting adj. and later phase-shift v.

Science.

A circuit, device, etc., which introduces a change in the phase of an oscillation or waveform; (Electrical Engineering) a transformer which alters the power factor in an A.C. circuit by changing the phase relationship of voltage and current.
