This function implements a Finite Impulse Filter.
Finite impulse filters take an input x and a co-efficient array b to generate an output y such that:
\f$y[n] = \sum_{i = 0}^N b_i . x[n]\f$
◆ af_fir()
C Interface for finite impulse response filter.
Parameters
| [out] | y | is the output signal from the filter |
|---|---|---|
| [in] | b | is the array containing the coefficients of the filter |
| [in] | x | is the input signal to the filter |
