The exponential filter is a typical [http://en.wikipedia.org/wiki/Low-pass_filter low pass filter]. The magic euler number and the associated mathematical funtion exp() plays a major role here. As the name implies, lower frequencies can pass this filter while higher frequencies are cut. The frequency where only half of the input signal reaches the output is called cutoff frequency. This cutoff frequency is defined by the parameter <filter-time> and resolves as cutoff-frequency = 1/(2*pi*cutoff-frequency).
Example: a 1Hz first order low pass filter
<filter>
  <type>exponential</type>
  <filter-time>0.16</filter-time>
  <input>/some/input</input>
  <output>/some/output/<output>
</filter>
