Abstract

Elimination of high frequency noise pollution emanating from a cathode ray tube (CRT) display assembly is of critical concern to individuals using data processing equipment. Typically a CRT display operates with a horizontal drive frequency within the audible range, such as in the 15 to 16 KHz range, and it is this frequency that must be eliminated.
