就一般滤波器而言,我们知道。当滤波器有关参数发生变化时,就会严重影响滤波器的性能。对于自适应带阻滤波器而言,将会怎样呢?由下面的分析看到,当误差在一定范围内时,自适应带阻滤波器仍保持良好的性能。正因为如此,将自适应带阻滤波器应用在频域内的以声消声中,就能得到较为 As far as general filters are concerned, we know. When the filter-related parameters change, it will seriously affect the performance of the filter. What will happen to an adaptive bandstop filter? The following analysis shows that the adaptive bandstop filter maintains good performance when the error is within a certain range. Because of this, the application of adaptive band-stop filter in the frequency domain of acoustic noise cancellation, we can get more
