FilterTool  Tool                   

In the complex world of digital filtering, there are a few basic types that stand out as useful in the analysis of neuronal spike train data: lowpass, highpass, bandpass, and bandstop. The FilterTool offers each of these options in a simplified graphics display, with user-selectable cutoff frequencies. You’re given the flexibility to select basic filter parameters that best suit your input data, while keeping the underlying filter construction fixed.
