PURPOSE:To realize a high order deflection correction waveform in multi- standard with a small scale circuit. CONSTITUTION:An output of a ROM 3 is fed to a multiplier 7 and a register 8 via a bus line 6, an output of a RAM 4 is fed to a multiplier 7, an output of the multiplier 7 and the register 8 is selected by a selector 9 and fed to an adder 10. Then the output of the adder 10 is fed to accumulators 11, 12 and the output of the accumulator 12 is fed to the adder 10 and an output of the accumulator 11 is fed to the RAM 4, the multiplier 7 and the register 8 via a bus line 6. Moreover, the operation of the ROM 3, RAM 4, multiplier 7, registers 8, 9, adder 10 and accumulators 11, 12 is controlled by a signal from an instruction ROM 2. |
