WebOct 23, 2024 · For an FIR filter, for a given cutoff frequency, the slope of the impulse response plot ( H(f) vs f) is steeper for a higher order filter. So, to achieve higher attenuation for the undesired frequency range, you increase the filter order. But what happens when the filter order is so high that the impulse response is an ideal box function? WebFiltering can be used to condition time series data in multiple ways: High-pass filters remove low-frequency (slow) noise and pass high-freqency signals. Low-pass filters remove high-frequency noise and thus smooth the data. Band-pass filters allow only certain frequencies and filter everything else out. Notch filters remove certain frequencies.
