METHOD FOR TRANSMITTING DIGITAL SIGNAL

摘要

PURPOSE:To suppress the waveform of a synchronizing signal from being deformed due to the interference between codes in case of a long range transmission when a signal pattern violating the rule of a data modulating system is used to a frame synchronizing pattern section to part each frame from plural frames. CONSTITUTION:A digital signal train is split into plural frames having a prescribed number of bits and the one frame is constituted of the frame format. The first 4 bits are used as a frame synchronizing pattern section S and the 5th-28th bits are used as a digital audio sampling data. The tail 2.5-bit part of the frame synchronizing pattern (preamble) of the head 4-bit is constituted so that the 1-bit length of the inverting interval is arranged next to the 1.5-bit as the main synchronizing period.
