Field Documentation

◆ numStages

uint8_t riscv_biquad_cascade_df2T_instance_f64::numStages

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

◆ pCoeffs

const float64_t* riscv_biquad_cascade_df2T_instance_f64::pCoeffs

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

◆ pState

float64_t* riscv_biquad_cascade_df2T_instance_f64::pState

points to the array of state coefficients. The array is of length 2*numStages.
