<p>PURPOSE:To provide an electronic muffler for performing a stable operation for which a silencing level is low. CONSTITUTION:Error signals are band-limited by a digital filter 19, a window function is multiplied with a tap coefficient by a computing element 34 and the tap coefficient of the digital filter 14 is substituted in an adaptive digital filter 16 at the time of activating the adaptive filter 16 or when a fault is generated. Thus, this electronic muffler for performing the stable operation for which the silencing level is low can be obtained.</p> |
