parametronn.

Brit.

/pəˈramᵻtrɒn/, U.S.

/pəˈræməˌtrɑn/

Origin: Formed within English, by derivation. Etymons: parametric adj.¹, -on suffix¹.

Etymology: < parametr- (in parametric adj.¹) + -on suffix¹, perhaps reinforced by possible blending of parametric adj.¹ and -tron (in electronic adj.: compare -tron suffix). Compare Japanese parametoron (E. Goto 1955, in Denki Tsūshin Gakkai Zasshi 30 770).The word was probably coined by E. Goto (in English) c1954: compare quot. 1956.

Electronics.

A digital storage element consisting of a parametric oscillator in which a binary digit is represented by the phase (0 degrees or 180 degrees, corresponding to 1 or 0) of the output signal relative to that of an applied reference signal of the same frequency.
