+  @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
+
+  @par           Coefficient and State Ordering
+                   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> for each channel.
+                   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.
