... Philips Semiconductors Terrestrial Digital Sound Decoder (TDSD2) Channel coding Time-slots are encoded as biphase mark data. Each bit transmitted is represented by a symbol comprising two consecutive binary states. The first state of a symbol is always different from the second state of the previous symbol. The second state of the symbol is identical to the first if the bit being transmitted is logic 0, however it is different if the bit is logic 1 (see Table 7) ...
