CIRCUIT FOR THE COMPENSATION OF THE HORIZONTAL COMPONENT OF THE EARTH'S MAGNETIC FIELD FOR A COLOUR PICTURE TUBE OF A HIGH-RESOLUTION MONITOR

摘要

The circuit comprises a probe (6) for detecting a horizontal magnetic field and first and second circuit means (15, 17) driven by said probe (6) so as to create respective axial and lateral components of compensation of the horizontal magnetic field, that are of equal direction and intensity, but of opposite sign to that of the magnetic field under test.
