On digital filtering of auditory brainstem responses

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.
