Abstract
A computer-implemented method to decode a digital signal includes following steps. A micro control unit (MCU) receives a digital signal. The MCU reads a low voltage period of the digital signal and stores a time duration of the low voltage period into a first register as a value TL. The MCU reads next high voltage period of the digital signal and stores a time duration of the high voltage period into a second register as a value TH. The MCU reads the value TL of the first register and the value TH of the second register, and computes a ratio TR=TH/TL. The MCU compares the ratio TR with two predetermined values M and N, if TR=M, the decoded result is a logical '1.' If TR=N, the decoded result is a logical '0.'
