Software Listing: Digital Filtering
- Median Filtering
- License: Shareware

The median filter is a nonlinear digital filtering technique, often used to remove noise with Laplacian distrinution. The main idea of the median filter is to run through the signal entry by entry, replacing each entry with the median of neighboring entries. The pattern of neighbors is called the "window", which slides, entry by entry, over the entire signal..

- Price: 0.00

SpikoRT helps monitor extracellular potentials in real-time. Extracellular signals acquired from an analog input are separated by digital filtering into field potentials and multiunit activity, which are fed into fast (1s) and slow (15min) graphs..
