ABSTRACT:
A receiving apparatus includes a unit detecting a specific-bit sequence included in a data sequence, a unit counting, as a count value n1, a first number of oscillations during a 1-bit-wide period of a first bit of the specific-bit sequence, and to count, as a count value n2, a second number of oscillations during a 1-bit-wide period of a second bit of the specific-bit sequence, a unit generating, when it is determined that the n1is not less than the (n2−a) and is not more than the (n2+a) (a=1,2, . . . ), a timing of n1/2, fractions of which are carried, for the first bit to a third bit of the specific-bit sequence, and to generate a timing of n1for a fourth bit and subsequent bits, and a unit acquiring a data sequence from the data sequence at the timing n1/2 and the timing n1.
