Detailed Description

[Filter] A simple first-order low-pass filter

Author: Jan Benda

The input x(t) is filtered with the ordinary differential equation

$\tau \frac{dy}{dt} = x - y$

to result in the low-pass filtered output y(t). The cut-off frequency of the filter is at

$f_c = \frac{1}{2 \pi \tau}$

Add the low-pass filter with the following lines to a relacs.cfg file:

*FilterDetectors
  Filter1
        name: LV-1
      filter: LowPass
  inputtrace: V-1
        save: false
        plot: true
  buffersize: 500000

Options

tau=1000ms: Filter time constant (number)

Version: 0.2 (May 12 2012)
