Receiving apparatus, receiving method, computer readable medium storing receiving program, and manufacturing method

A receiving method comprising:

• a computer receiving a plurality of pulses including a synchronization pulse having a predetermined synchronization pulse width and a data pulse having a data pulse width corresponding to a value of data;
• the computer storing, in a buffer, pulse information indicating a pulse period or pulse width of each of the plurality of pulses;
• the computer searching for pulse information indicating a pulse period or pulse width that falls within a synchronization pulse acceptable range from among a plurality of pieces of pulse information stored in the buffer for the plurality of pulses;
• the computer detecting whether pulse information stored in the buffer for a second pulse at a predetermined location relative to a first pulse corresponding to the pulse information searched for indicates a pulse period or pulse width that falls within a data pulse acceptable range;
• and
• the computer identifying the first pulse as the synchronization pulse on condition that the pulse information of the second pulse indicates a pulse period or pulse width that falls within the data pulse acceptable range.

A computer-readable recording medium having recorded thereon a receiving program that, when executed by a computer, causes the computer to function as:

• a receiving unit configured to receive a plurality of pulses including a synchronization pulse having a predetermined synchronization pulse width and a data pulse having a data pulse width corresponding to a value of data;
• a pulse storing unit configured to store, in a buffer, pulse information indicating a pulse period or pulse width of each of the plurality of pulses;
• a searching unit configured to search for pulse information indicating a pulse period or pulse width that falls within a synchronization pulse acceptable range from among a plurality of pieces of pulse information stored in the buffer for the plurality of pulses;
• a detecting unit configured to detect whether pulse information stored in the buffer for a second pulse at a predetermined location relative to a first pulse corresponding to the pulse information searched for by the searching unit indicates a pulse period or pulse width that falls within a data pulse acceptable range;
• and
• an identifying unit configured to identify the first pulse as the synchronization pulse on condition that the pulse information of the second pulse indicates a pulse period or pulse width that falls within the data pulse acceptable range.
