The high pass filter is a typical [http://en.wikipedia.org/wiki/High-pass_filter high pass filter]. The magic euler number and the associated mathematical funtion exp() plays a major role here. As the name implies, higher frequencies can pass this filter while lower 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). It is commonly known as a wash-out filter | The high pass filter is a typical [http://en.wikipedia.org/wiki/High-pass_filter high pass filter].
