#154762 - 64 samples is big for a median filter ... Responding to: ???'s previous message |
Common median filters are in the 5 to 9 samples range, and they are more useful for eliminating spikes/glitches from the signal than actual noise. They're also quite nonlinear and introduce random (signal-dependent) phase shifts, which may or may not be a problem for your application.
Have you thought about using a digital filter (even a simple one like a moving average) to reduce the noise ? |
