phasitronn.

Brit.

/ˈfeɪzᵻtrɒn/, U.S.

/ˈfeɪzəˌtrɑn/

Origin: Formed within English, by derivation. Etymons: phase n.², -i- connective, -tron suffix.

Etymology: < phase n.² + -i- connective + -tron suffix.

Electronics. Now rare.

An electron tube suitable for phase-modulating a wave by large amounts, in which a pattern of beams emitted radially from a central cathode passes through a slotted cylindrical anode to a coaxial second anode, the pattern of beams being both rotated at a steady rate by a three-phase supply and modulated by a varying axial magnetic field that advances and retards the beams and thereby also the phase of the current at the second anode.

1946 Electronics Oct. 108/2 The carrier frequency.., after one stage of amplification, is used to drive a phase-splitting network to provide three-phase voltages for the input deflector grids of a ‘Phasitron’ tube.

1946 Electronics Oct. 111/2 Since the Phasitron is modulated by a magnetic field, fields other than those produced by the audio input will cause noise modulation of the carrier.

1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) V. 514/1 An improvement in the phase-modulation method is provided by a special tube called the phasitron, which is capable of increasing the amount of phase shift.
