Abstract
A detecting device for detecting a stack light state includes a low-pass filter configured to perform low-pass filtering on an input signal to generate a first output voltage; and a logic circuit coupled to the low-pass filter and configured to determine the stack light state according to the first output voltage; wherein the input signal is a pulse width modulation signal and a voltage level of the first output voltage is between a highest voltage level and a lowest voltage level of the pulse width modulation signal.
