Abstract:
A data synchronizing signal detecting device for performing a data sync signal detection by collating a data bit string output from a data discriminator with a data sync signal pattern,wherein said data synchronizing signal detecting device collates the data bit string with the data sync signal pattern by dividing the data bit string into even-numbered bit strings having consecutive â€œ1â€  bit strings except for a bit string having at least one end portion having one â€œ1â€  bit string and another end portion having another â€œ1â€  bit string, and bit strings constituted by at least one odd-numbered bit string having consecutive â€œ0â€  bit strings between the â€œ1â€  bit strings, and wherein said data synchronizing signal detecting device respectively matches said even-numbered bit strings and said bit string constituted by at least one odd-numbered bit string with the data sync signal pattern, thereby performing a data sync signal detection.
