摘要:
Methods and apparatus are provided for receiving a first signal and generating an output signal indicative of radio data system (“RDS”) information. A receiver circuit of the invention can include mixer circuitry, lowpass filter circuitry, downsampler circuitry, and decoder circuitry. Advantageously, the receiver circuit can operate entirely within the digital domain, promoting interoperability with digital frequency modulation (“FM”) demodulator circuitry.
