Field Documentation

iPostShift

int8_t tpt_biquad_cascade_df1_q15_s::iPostShift

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

pCoeffs

const q15_t* tpt_biquad_cascade_df1_q15_s::pCoeffs

Points to the array of coefficients. The array is of length 5 * uStages.

pState

q15_t* tpt_biquad_cascade_df1_q15_s::pState

Points to the array of state coefficients. The array is of length 4 * uStages.

uStages

uint16_t tpt_biquad_cascade_df1_q15_s::uStages

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