Rds Demodulator Ic Semiconductor

Since 1988 most European national broadcaststations transmit RDS- code beside their Audio signals. RDS means Radio S1A0905 Data System and was originally intended to give people in their cars additional informa- tion about the weather or traffic(jams). But RDS has grown out to one big channel of information. Radiostations send their name, the time (with DCF-77 accuracy), their type of music (format) and even more. The digital data of RDS are multiplexed into an FM Radio wave using a sub-carrier of 57kHz. The transmission rate of RDS data is 1.1875kbit/sec. The transmission rate of RDS data is 1.1875kbit/sec, and RDS data are encoded by differential encoding method. Then the encoded RDS data are modulated by BPSK using a Clock of 1.1875kHz. The modulated RDS data is are modulated by Carrier suppressed amplitude modulation using a sub- Carrier of 57kHz. And that signal are multiplexed into an FM Radio wave. By Samsung Semiconductor, Inc.
