@brief Instance structure for the Q15 Biquad cascade filter.

Fields

numStages: i8

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

pState: *mut q15_t

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

pCoeffs: *const q15_t

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

postShift: i8

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