This function implements a Infinite Impulse Filter.
Iinite impulse filters take an input x and a feedforward array b, feedback array a to generate an output y such that:
\(\sum_{j = 0}^Q a_j . y[n] = \sum_{i = 0}^P b_i . x[n]\)
C++ Interface for infinite impulse response filter.
| [out] | y | is the output signal from the filter | 
| [in] | b | is the array containing the feedforward coefficients | 
| [in] | a | is the array containing the feedback coefficients | 
| [in] | x | is the input signal to the filter |
