Filter Coefficient Arrays, Number Format Handling and Input/Output History Parameters.
The NPNZ_FILTER_PARAMS_t data object holds all configuration parameters of the compensation filter. These parameters include pointers to external arrays of filter coefficients, error and control history as well as number format normalization parameters like pre- and post- scalers.
