Abstract :
Proposes a method for detection of action potentials (APs) under low signal-to-noise ratio conditions. It is based on multiresolution analysis. Three parameters are used for detection. Two of them are for determining if there is an AP or not, and the other is for the estimation of waveforms. The authors´ method provides better estimated waveforms than the conventional de-noising approach.
