	  <p>
	Signal pre-processing in LTPDA consists on a set of functions intended to pre-process data 
	prior to further analysis. Pre-processing tools are focused on data sampling rates manipulation, 
	data interpolation, spike cleaning and gap filling functions.
  </p>
  <p>
	The following pages describe the different pre-processing tools available in the LTPDA toolbox:
	<ul>
		<li><a href="downsample.html">Downsampling data</a></li>
		<li><a href="upsample.html">Upsampling data</a></li>
		<li><a href="resample.html">Resampling data</a></li>
		<li><a href="interp.html">Interpolating data</a></li>
		<li><a href="spikeclean.html">Spikes reduction in data</a></li>
		<li><a href="gapfill.html">Data gap filling</a></li>
