[f. alteration of fantastic a. and n.: see -tron.]
A 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).
