Device and Method For Setting Adjustment Control

摘要

A device and a method are provided for setting adjustment control for a device. The method comprises acts of generating a time base signal that is synchronized to an Alternating Current (AC) voltage, and generating a modulated AC voltage in response to an input control signal, which is referenced to the time base signal. The modulated AC voltage has a setting pattern that is formed by interrupting the AC voltage. The method further comprises acts of using the modulated AC voltage to change the device to a desired setting. The desired setting is determined from the corresponding setting pattern.
