- * @brief Initialization function for the floating-point transposed direct form II Biquad cascade filter.
- * @param[in,out] *S points to an instance of the filter data structure.
- * @param[in] numStages number of 2nd order stages in the filter.
- * @param[in] *pCoeffs points to the filter coefficients.
- * @param[in] *pState points to the state buffer.
- * @return none
- *
- * <b>Coefficient and State Ordering:</b>
- * \par
- * The coefficients are stored in the array <code>pCoeffs</code> in the following order:
- * <pre>
- * {b10, b11, b12, a11, a12, b20, b21, b22, a21, a22, ...}
- * </pre>
- *
- * \par
- * where <code>b1x</code> and <code>a1x</code> are the coefficients for the first stage,
- * <code>b2x</code> and <code>a2x</code> are the coefficients for the second stage,
- * and so on. The <code>pCoeffs</code> array contains a total of <code>5*numStages</code> values.
- *
- * \par
- * The <code>pState</code> is a pointer to state array.
- * Each Biquad stage has 2 state variables <code>d1,</code> and <code>d2</code>.
- * The 2 state variables for stage 1 are first, then the 2 state variables for stage 2, and so on.
- * The state array has a total length of <code>2*numStages</code> values.
- * The state variables are updated after each block of data is processed; the coefficients are untouched.
