Abstract
A demodulation circuit of the communication control system is disclosed, in which the rising edge and the falling edge of a symbol or a one-bit data subjected to pulse width modulation as inputted from a transmission path are detected. The time width of a high-level section or a low-level section of the symbol or the one-bit data is measured on the basis of the result of edge detection. The time width thus measured is compared with a reference time width set in advance. According to the result of comparison, the sampling timing for the high-level section and the low-level section is adjusted respectively. The sampling timing thus adjusted is used to demodulate the data requiring demodulation including the symbol and the one-bit data.
