CORRECTION OF LINEARITY ERRORS

摘要

In order to compensate for currents which are induced in a convergence yoke (16) by a deflection yoke (14), a pulse of current is injected into an amplifier (26) which receives the convergence waveform (from 28) so as to correct or compensate for the induced current. One way of generating the compensating pulse is by delaying a horizontal retrace pulse (36).
