Instance structure for the high precision Q31 Biquad cascade filter.
Definition at line 3568 of file arm_math.h.
| uint8_t numStages |
number of 2nd order stages in the filter. Overall order is 2*numStages.
Definition at line 3570 of file arm_math.h.
| q31_t* pCoeffs |
points to the array of coefficients. The array is of length 5*numStages.
Definition at line 3572 of file arm_math.h.
| uint8_t postShift |
additional shift, in bits, applied to each output sample.
Definition at line 3573 of file arm_math.h.
| q63_t* pState |
points to the array of state coefficients. The array is of length 4*numStages.
