IIRCoeff

IIRCoeff 1:

Implementation of an Infinite Impulse Response filter (IIR).

The documentation of the corresponding PLC function block can be found here: FB_FTR_IIRCoeff

Configuration parameters

Coefficient A: the coefficients a_k (denominator) [a_0, a_1, a_2,..._, a_N] can be chosen freely.
Coefficient B: the coefficients b_k (numerator) [b_0, b_1, b_2,..._, b_M] can be chosen freely.

Initial Values (optional): initial values define the internal state of the filter.

Output values

Output: manipulated output signal.
