Beschreibung
Zusammenfassung:	A raster distortion correcting signal synthesizer includes a multiplier, an adder, a memory for storing data and a coefficient, and a controller for controlling the multiplier, adder and memory in accordance with a count value of a horizontal sync. signal. The controller calculates a desired raster distortion correcting signal of a high order by utilizing the multiplier and adder on the basis of the count value, and multiplies the count value by a predetermined coefficient to obtain a new count value.
