Comparison of the performance of a median (solid black) and a FIR filter (dashed black) for removing noise and unwanted pulses from single channel current recordings (grey). Both filters are tuned to a cut off duration of 0.5 ms to remove pulses with pulse duration, d, less than 0.5 ms and pass the pulses with duration greater than 0.5 ms. The duration of the left pulse is slightly less that 0.5 ms (should be suppressed by the filter) and the duration of the right pulse is slightly more than 0.5 ms (should pass through the filter).
