Abstract
A correction signal generating circuit for a television receiver includes a counter for counting a pulse synchronized with a horizontal sync signal, a memory for storing correction data and a coefficient, and a unit for multiplying and adding contents of the counter and the memory. A signal feedback loop supplies an output from the multiplying and adding unit to an input thereof, and a control unit controls operation of the memory and the multiplying and adding unit, thereby generating a correction signal.
