quantize, analyze and generate Verilog or C code of a designed filter according to the given
specifications

format moves the respective poles to quantized locations and makes the system experience more
quantization noise at places with wider gaps. The structure given in Figure 3.30 creates a uniform
rectangular grid and helps the designer to exactly model the quantization noise independent of
location of its double-precision poles and zeros (r and y are the radius and angle of the complex

conjugate poles).
