本文探讨了数字信号处理中涉及的转移函数结构，包括直接呈现增益的块结构，一阶和二阶转移函数的乘积形式，以及部分分式展开。文章还深入介绍了针对嵌入式处理器的固定点设计时可能出现的问题，并详细阐述如何在MATLAB工作空间和Simulink模型之间使用DSP System Toolbox块进行固定点数据的传递。最后，讨论了Fixed-Point Designer™ fi对象在Simulink模型中的应用方法。
Structure where coefficients of the transfer function appear directly as Gain
blocks.
Transfer function that is written as a product of first-order and second-order
transfer functions.
Transfer function that is expanded into partial fractions.
Set of fundamental operations for the processor for a given digital filter.
Describes issues that arise when targeting a fixed-point design for use on an
embedded processor.
