DSP System Toolbox 快速入门
DSP System Toolbox™ 提供算法、App 和示波器，用于在 MATLAB® 和 Simulink® 中设计、仿真和分析信号处理系统。您可以对用于通信、雷达、音频、医疗设备、物联网和其他应用的实时 DSP 系统进行建模。
使用 DSP System Toolbox，您可以设计和分析 FIR、IIR、多速率、多级和自适应滤波器。您可以从变量、数据文件和网络设备流式传输信号以进行系统开发和验证。通过时域示波器、频谱分析仪和逻辑分析仪，您可以对流信号进行动态可视化和测量。在桌面原型构建和嵌入式处理器（包括 ARM® Cortex® 架构）部署方面，该工具箱支持 C/C++ 代码生成。它还支持从滤波器、FFT、IFFT 和其他算法进行位精确定点建模和 HDL 代码生成。
算法采用多种形式，包括 MATLAB 函数、System object 和 Simulink 模块。
