Chapter 15Modeling DSP Components

Modeling DSP components is different from modeling other constituent parts of a communications system. The model of an analog device is based on mathematical descriptions of processes that are defined by the laws of physics, often with only limited observability of all the various processes actually involved. Modeling of a DSP device is simplified by the the fact that the model of a DSP device is based on mathematical descriptions of processes that are defined mathematically. On the other hand, modeling of a DSP device is often complicated by the need to model the effects of quantized Signal values, quantized coefficients, and finite-precision arithmetic. When quantization effects are included, otherwise linear ...
