DSP Implementation of Hysteresis Control for Active Noise Control

능동소음제어를 위한 히스테리시스 제어의 DSP 구현

This paper presents active silencer by hysteresis control method using DSP-scheme and shows it audible noise reduction effect. Pentium processor and sound blaster 16 are used for its implementation. The sound blaster 16 executes A/D, D/A conversion and is used operating source of loudspeaker for cancelling.
