Field Documentation

◆ numStages

uint32_t numStages

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

◆ pCoeffs

const float32_t* pCoeffs

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

◆ pState

float32_t* pState

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