Broadcast Circuit Arrangements TRIZ Cases
- FM Modulation Detection Using Autocorrelation Under Noise
Autocorrelation-based FM modulation estimation rejects noise better than peak detection, enabling cleaner filter bandwidth setting under weak signals.
- Re-multiplexing Apparatus for Synchronizing 2K and 4K Broadcast Data
A re-multiplexing apparatus inserts delay control packets to synchronize broadcast data outputs across different transmission lines.
- Receiver Pilot Tone Extraction via 19 kHz Frequency Shifting
Frequency shifting centers the pilot tone at DC, suppressing upper sideband noise and improving audio quality without complex hardware.
- FM Pilot Detector Signal Accumulation for Stereo Mono Discrimination
Signal accumulation in a pilot detector filters noise interference, enabling precise stereo versus mono discrimination without complex filter structures.
- Adaptive FM Receiver Pilot Signal Noise Separation
An adaptive FM receiver uses a notch filter to separate the pilot signal from noise, enabling dynamic mono or stereo decoding based on real-time signal quality.
- In-Vehicle Audio Router Using Optical Network Segmentation
Optical splitter and multi-channel router segment in-vehicle audio networks, reducing system complexity and restoration time while enhancing noise resistance.
- Adjacent Channel Noise Detection in FM Receivers
A radio receiver compares frequency deviations above and below the center frequency to identify adjacent channel noise.
