Gain Control TRIZ Cases
- Audio Signal Processing Using Auto-Regressive Residual Modeling
Auto-regressive modeling creates a residual signal from input audio, reducing parameter complexity for mixing and mastering.
- Semiconductor Device with Adaptive Amplifier Circuit for Low Power Display
Adaptive amplifier circuit determines current gain via sensing circuit node comparison, resolving power consumption versus luminance trade-offs.
- Audio Signal Sound Quality Correction via Feature Parameter Segmentation
A sound quality correction apparatus calculates feature parameters to differentiate speech and music signals for adaptive processing.
- Columnar Reflector Structure for Acoustic Frequency Balance
Randomly arranged columnar reflectors with varying diameters diffuse sound waves to eliminate periodic coloration and improve low-range absorption.
- Vehicle Interior Noise Control via Conversation Intent Detection
A vehicle control device detects occupant conversation intent using sensors and image recognition to adjust interior noise levels automatically.
