Abstract:
A data synchronizing signal detecting device, comprising:means for separating a data bit string having a data sync signal detection pattern output from a data discriminator into a corresponding sync signal pattern, a plurality of bits to be compared and a bit not to be compared to produce groups having a predetermined number of bits from said plurality of bits to be compared; means for comparing each of said groups with said corresponding data sync signal pattern to acquire a coincidence; and means for receiving an output from each of said compare means and detecting a data sync signal when number of coincided groups is equal to or greater than a threshold value, wherein said bit string patterns to be compared are separated into odd-numbered bit strings and even-numbered bit strings to produce said groups from a combination of the odd-numbered bit strings and a combination of the even-numbered bit strings.
