WebRemove Spikes from a Signal. Sometimes data exhibit unwanted transients, or spikes. Median filtering is a natural way to eliminate them. Consider the open-loop voltage across the input of an analog instrument in the presence of 60 Hz power-line noise. The sample rate is 1 kHz. load openloop60hertz fs = 1000; t = (0:numel (openLoopVoltage) - 1)/fs; WebUse the filtfilt function to process the data. ybs = filtfilt (df,yds); Finally, upsample the signal to bring it back to the original audio sample rate of 44.1 kHz which is compatible with audio sound cards. yf = interp (ybs,10); Fs = Fs*10; Take a final look at the spectrum of the original and processed signals.
