Detailed Description

Instance structure for the high precision Q31 Biquad cascade filter.

Field Documentation

pCoeffs

const q31_t* tpt_biquad_cas_df1_32x64_ins_q31_s::pCoeffs

points to the array of coefficients. The array is of length 5*numStages.

pShift

uint8_t tpt_biquad_cas_df1_32x64_ins_q31_s::pShift

additional shift, in bits, applied to each output sample.

pState

q63_t* tpt_biquad_cas_df1_32x64_ins_q31_s::pState

points to the array of state coefficients. The array is of length 4*numStages.

uStages

uint8_t tpt_biquad_cas_df1_32x64_ins_q31_s::uStages

number of 2nd order stages in the filter. Overall order is 2*numStages.
