Analogue Recording/Reproducing TRIZ Cases
- Frequency-Warped Audio Equalizer for Accurate Low-Cost Filtering
Frequency warping improves equalizer band isolation, delivering FIR-like accuracy with lower computing load than conventional filters.
- Segment-Based Audio Equalization for Dynamic Sound Field Expansion
Audio is split into segments and equalizer settings are adapted from extracted features to enlarge the sound field without manual tuning.
- Frequency-Warped Audio Equalizer for Precise Band Isolation
Frequency warping improves equalizer accuracy and band isolation while avoiding the high compute cost of FIR filtering.
- Semiconductor Interrupt Pattern Generator for High-Speed Serial Loopback Testing
An interrupt pattern generator and selector insert test frames into serial data streams, enabling high-speed loopback testing with low-cost equipment.
- Turntable with Integrated Analog-to-Digital Converter for USB Output
A turntable integrates an analog-to-digital converter and USB controller to generate digital signals directly from the phono cartridge.
- Universal Tape Cartridge Characterization via MAM Calibration
Pre-characterizing virgin cartridges in controlled environments eliminates repeated on-site calibration time.
- Voice-Based Device Authentication and Connection Method
Processor generates voice-based authentication data to establish secure communication links, reducing manual interaction complexity.
- Single SoC HDD Architecture with Matched Impedance Termination
A single system on chip controls multiple hard disk drive preamplifiers through transmission lines intersecting at a matched point compensation node.
