<p>Decimation is performed in two stages;</p>
<ul>
  <li>First, an anti-aliasing filter is applied to the data to limit frequencies to 0.4 * Fs, where Fs is the sampling rate after downsampling.
    <blockquote>
      <p>The filter is a Type I Chebyshev lowpass filter of order 3-13 with nominal 0dB magnitude response in the passband and a passband ripple of 0.05dB. An o
