Abstract :
We describe the application of an analog fuzzy processor to a loudspeaker system. The introduction of this audio processor between the input electric signal and the power amplifier results in a remarkable reduction of the distortion of reproduced sounds. Measurements performed on a commercial loudspeaker, using a demonstration board, show that total harmonic distortion can be reduced by several dBs using the proposed audio processor
