ABSTRACT:
An analog multiplier is used for generating an output signal that is coupled to a convergence winding of a projection television. The analog multiplier multiplies a horizontal rate sawtooth signal with a vertical rate parabola signal. To prevent temperature related drift, tolerances and component aging from affecting the output signal, the multiplier is calibrated during each vertical blanking interval.
