Parameter structure for Direct Form 2 biquad filter.
_q15 msp_biquad_df2_q15_params::bias |
DC bias added to input of the biquad operation.
const _q15* msp_biquad_df2_q15_params::coeffs |
Pointer to filter coefficient vector of length 7 in format a0, a1, a2, a3, b1, b2, b3.
uint16_t msp_biquad_df2_q15_params::length |
Length of the source data, must be a multiple of two.
_q15 msp_biquad_df2_q15_params::Q1 |
State of the biquad operation. Initialize to zero and pass the previous state to the next biquad operation when continuous operation is desired.
_q15 msp_biquad_df2_q15_params::Q2 |
State of the biquad operation. Initialize to zero and pass the previous state to the next biquad operation when continuous operation is desired.
_q15 msp_biquad_df2_q15_params::sumMax |
Maximum of the output vector.
_q15 msp_biquad_df2_q15_params::sumMin |
Minimum of the output vector.
