Radio Data System/Radio Broadcast Data System TRIZ Cases
- Single FM Tuner Station List Using Pre-Cached RDS Data
Pre-cached RDS/RBDS station data lets a single FM tuner show frequencies and program info quickly without long mute periods.
- DARC Demodulation Circuit Using Orthogonal 76 kHz Signal Extraction
Orthogonal 76 kHz oscillations and low-pass filtering recover DARC data from FM multiplex signals while suppressing harmonics and noise.
- RDS Frequency Switching Using Accumulated AF Lists
By storing and reusing accumulated AF lists, RDS switching avoids futile frequency changes and reduces sound breaks in weak signals.
- Multi-Device Connection Prioritization Under Communication Resource Limits
A device selects a limited set of external connections by signal strength or distance to preserve battery, antenna, and time resources.
