Abstract

PURPOSE: To prevent the vibration of digigal codes to stabilize a display screen by giving hysteresis to the I/O characteristic of an A/D converter in a TV game unit.
CONSTITUTION: An analogue signal from variable resistor 31 is inputted through switch 32 and is converted by A/D converter 33, and the output digital code is stored in 35. Then, stored contents are compared with the digital code, which is next subjected to A/D conversion in 33, by 36, and the output of A/D converter 33 and the output obtained by adding "1" to the output above by 39 are switched by switch 7 according to the comparison result and are outputted. As a result, hysteresis can be given to I/O characteristic.
