Aspects of a method and system for a radio data service (RDS) demodulator for a single chip integrated Bluetooth and frequency modulation (FM) transceiver and baseband processor are presented. Aspects of the system may include circuitry on a single chip that enables demodulation of an RDS signal, filtering of the RDS signal, and detection of binary bits in the filtered RDS signal. The filtered RDS signal may be generated by filtering the RDS signal based on a raised cosine filter, or a doublet filter. In general, the RDS signal may also be filtered by a filter that is a first, or greater derivative of a Gaussian filter in either the time or frequency domain. Aspects of the method may include demodulating the RDS signal, filtering the RDS signal, and detecting binary bits in the filtered RDS signal.
