信号生成、操作和分析
创建、导入、导出、显示和管理信号
DSP System Toolbox™ 提供使用 MATLAB® 或 Simulink® 在时域和频域中分析、测量和可视化信号的工具。您可以生成和流式传输信号，对这些信号执行操作，并实时可视化变化。要动态可视化信号，请使用 Spectrum Analyzer、Time Scope、Array Plot 和 Logical Analyzer 模块或 System object。要了解有关流信号的更多信息，请参阅Introduction to Streaming Signal Processing in MATLAB。

Time Scope Measurements
Measure performance characteristics of a pulse width modulated sinusoid. The example contains a model, which you can modify to view the effects of parameter changes on rise time, fall time, overshoot, undershoot, pulse width, pulse period, and duty cycle measurements. The example also models a rising edge trigger and you can perform basic statistical operations (mean, median, RMS, maximum, minimum) and measure the frequency and period of the pulse period via cursors and peak finding.
