Auditory brainstem responses are very short events. Therefore, their signal processing has to be executed really carefully. Their latency and amplitude parameters, which are employed to indicate pathological changes, are especially sensitive to digital filtering. Consequently, we have studied appropriate nonrecursive and recursive filters for signals of auditory brainstem responses. Our results seem to refer to rather similar effects of both nonrecursive and recursive filters on the parameters of auditory brainstem responses.
听觉脑干反应是非常短暂的事件。因此,它们的信号处理必须非常谨慎地执行。用于指示病理变化的潜伏期和振幅参数对数字滤波特别敏感。因此,我们研究了适用于听觉脑干反应信号的非递归和递归滤波器。我们的结果似乎表明,非递归和递归滤波器对听觉脑干反应参数的影响相当相似。
