0 Introduction Signal Modulation is a modern technology that takes advantage of the limited resources available to enable additional functionality. The use of AC modulation dimming signal is the use of AC power supply to achieve the purpose of identifying fluorescent dimming signal. A traditional fluorescent dimming control Fluorescent dimming control, the existing practice is usually manually change the dimming control potentiometer resistance. In the circuit
