Signal Generation, Manipulation, and Analysis

Create, import, export, display, and manage signals

DSP System Toolbox™ provides tools for analyzing, measuring, and visualizing signals in the time and frequency domains using MATLAB^® or Simulink^®. You can generate and stream signals, perform operations on these signals, and visualize the changes in real time. To visualize signals dynamically, use the Spectrum Analyzer, Time Scope, Array Plot, and Logical Analyzer blocks or System objects. To learn more about streaming a signal, see 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.
