ABSTRACT:
The present invention relates to bit synchronization required for a data transmitting/receiving system. An average phase error between edges of an input waveform and edges of an ideal bit synchronous pattern generated internally is taken and the ideal bit synchronous pattern is shifted by the amount corresponding to the average error, so that a sampling signal is generated on the basis of that pattern. Thus, bit synchronization is established by means of software on microcomputor.
