Floating-Point to Fixed-Point Conversion of IIR Filters

Use the Fixed-Point Converter App to convert an IIR filter from a floating-point to a fixed-point implementation. Second-order sections (also referred as biquadratic) structures work better when using fixed-point arithmetic than structures that implement the transfer function directly. We will show that the surest path to a successful "float-to-fixed" conversion consists of the following steps:
