3. The key demodulation component in the chain is the phase derivative. The phase derivative takes the phase of the signal and creates a second signal that is composed only of the changes in frequency. This is then the demodulated signal. 4. The low pass filter is used to filter out fre...

The sine-demodulated signal corresponds to the coherent demodulation output. The cosine-demodulated signal is used for detection of phase error. The products of the 57 kHz RDS/RBDS signal with the sine/cosine waves are low-pass filtered with the filter specified in Sec. 1.7 of [ 1 ]. The...
