Detailed Description
class BiQuadFilterDF2< T >
Generic BiQuad (Bi-Quadratic) filter class, Direct Form 2 implementation.
Uses the NormalizingBiQuadFilterDF2 implementation for floating point types, and NonNormalizingBiQuadFilterDF2 for all other types.
Implements the following difference equation:
\[ y[n] = \frac{b_0 \cdot x[n] + b_1 \cdot x[n-1] + b_2 \cdot x[n-2] - a_1 \cdot y[n-1] - a_2 \cdot y[n-2]}{a_0} \]

Construct a new BiQuad (Bi-Quadratic) Filter object.
The coefficients \( b \) and \( a \) can be derived from the transfer function:
\[ H(z) = \frac{b_0 + b_1 z^{-1} + b_2 z ^{-2}} {a_0 + a_1 z^{-1} + a_2 z ^{-2}} \]
- Parameters
-
b_coefficients The coefficients of the transfer function numerator. a_coefficients The coefficients of the transfer function denominator.
