How to remove high frequency noise
WebHigh-frequency noise is due to components of a signal varying faster than the signal of interest. Removing high-frequency noise allows the signal of interest to be more compactly represented and enables more accurate analysis. A low-pass filter is a common techqnique for removing high-frequency noise in a signal.
