Figure 2-32a: Parameter tree node Filter (Filter tab).
Name: Unique name of the input signal. If this field is empty the corresponding input signal is deactivated.
Filter Type: The filter type is either a moving average filter, delay filter, IIR filter 2nd order (biquad), maximum filter, minimum filter, edge filter, rising edge filter, or falling edge filter.
Source S1: The name of the input signal.
Source S2: Optionally the resetting signal when S2 changes.
Order: Defines the window width (and also the number of storage locations). Note that the storage is scarce and the order number should be ≤ 100 for the moving average filter and the delay filter. For the moving average filter, the signal delay is given by half of the window width.
Rate Ratio: Defines the filter rate as a multiple of the cycle of the calculation signals. This value usually equals 1, and is used only to extend the window width without increasing the order.
Coefficients: The floating point coefficients of the IIR filter 2nd order (biquad) which can be looked up online via a biquad calculator.
Note that at least SICOLOG/SICO3/USBDL1 firmware version 1.0.25 is required for the filter implementations.
