time base
  • A circuit or device that provides the voltage or signal which deflects an electron beam across the screen of a CRT during each sweep. Such a circuit or device usually utilizes a sweep generator which produces sawtooth waves, thus providing for a linear scan of the spot across the screen. Used in CRT displays such as those of TVs and radars. Also called time-base generator (1).
