Patent ID: 8660172

Claim:
A pulse signal receiving apparatus comprising: a reception unit configured to receive a pulse signal modulated by a double-edge modulation scheme, the pulse signal including a first edge interval and a second edge interval, the second edge interval following the first edge interval; a measurement unit configured to measure the first and second edge intervals of the pulse signal, which has been received by the reception unit; a correction unit configured to correct the first edge interval, which has been measured by the measurement unit, by using a first value; a decoding unit configured to decode the pulse signal, of which the first edge interval has been corrected by the correction unit, so as to output a digital signal; and a detection unit configured to detect, as a second value, a deviation of the first edge interval, which has been corrected by the correction unit, the deviation being for a pulse-width reference value indicating a reference value of a width of the pulse signal, wherein the correction unit is configured to correct the second edge interval, which has been measured by the measurement unit, by using the second value.
