Noise Countermeasures and Audio Quality Improvement for Bluetooth Audio Devices
TDK Product Features
TDK's noise suppression filters provide both high noise suppressing effects and signal quality because they show very little change in characteristics with respect to AC and DC due to their material and structural designs where magnetic saturation is suppressed. While controlling audio distortions (THD+N / Total Harmonic Distortion + Noise) in audio lines (such as those for speakers, earphones, and microphones), they also show excellent effects in measures against deterioration in receiving sensitivity, measures against burst noise (TDMA/TDD), and measures against noise in class D amplifiers. They show excellent effects in emission noise countermeasures in power lines for LED lighting.
