Detailed Description

template<class T>
class HCascadedBiQuadFilter< T >

A generic cascaded biquad filter (a number of biquads cascaded efter each other).

Given a set of coefficients, usually calculated by a filterdesign tool - but they can be taken from one or several generic biquads (HHighpassBiQuad, HNotchBiQuad, etc.).

The parameters must be provided in the order: b0,1 b1,1 b2,1 a1,1 a2,1 b0,2 b1,2 b2,2 a1,2 a2,2 b0,... b1,... b2,... a1,... a2,... b0,N b1,N b2,N a1,N a2,N

The coefficients can either be defined as an array in the source code, or come from a file - use the factory method Create() to read such coefficients. (this is practical when you are finetuning a filter)

Examples: saq.cpp.
