  • Total harmonic distortion (THD) controlled clip detector and automatic gain limiter (AGL)
    Patent number: 10476446
    Abstract: The disclosed embodiments include an audio amplifier system configured to provide a total harmonic distortion (THD) controlled clip detector and an automatic gain limiter (AGL) solution for a closed-loop amplifier. The audio amplifier system is capable of maintaining high power output without hard distortion (i.e., hard clipping) for providing better acoustics, while preventing damage to the system.
    Type: Grant
