Detailed Description

Parameter structure for Direct Form 1 biquad filter.

Field Documentation

const _q15* msp_biquad_df1_q15_params::coeffs

Pointer to filter coefficients of length 5 in format b2, b1, b0, a2, a1.

uint16_t msp_biquad_df1_q15_params::length

Length of the source data, must be a multiple of two.

_q15* msp_biquad_df1_q15_params::stateBuffer

Pointer to an array of length four used to store the state of the biquad operation. When continuous operation is desired the previous state needs to be passed to the next biquad operation. This data block must be allocated in shared RAM when using LEASC.
