phantastronn.

Brit.

/fanˈtastr(ə)n/,

/fanˈtastrɒn/, U.S.

/fænˈtæstrən/,

/fænˈtæsˌtrɑn/

Origin: Formed within English, by derivation. Etymons: English phantastic , fantastic adj., -tron suffix.

Etymology: < phantas- (in phantastic, variant of fantastic adj.) + -tron suffix.

Electronics.

A pulse-generating circuit in which a brief triggering pulse produces at one electrode a longer pulse whose duration is proportional to an applied control voltage, and at another electrode a linear sweep voltage of the same duration (which can then be used to generate another pulse that will occur at a definite interval after the triggering pulse).
