DEGAUSSING CIRCUIT

摘要

PURPOSE: A degaussing circuit is provided to be capable of detecting a horizontal frequency from a horizontal deflection wave received from a horizontal deflection circuit; and a degaussing coil for eliminating the magnetic field caused by a DC component from the horizontal frequency received from the degaussing control section. CONSTITUTION: A degaussing controller(17) detects a horizontal frequency from a horizontal deflection circuit(16). A degaussing coil(D-COIL) is connected to the degaussing controller(17) for eliminating an earth magnetic field caused by a DC component from the horizontal frequency received from the degaussing controller. The degaussing controller includes a high frequency filter(17a) connected to the horizontal deflection circuit(16) for filtering the horizontal deflection wave received from the horizontal deflection circuit to block a horizontal high frequency thereof.
