Spectrum analyzer software performs the signal spectral analysis tasks traditionally handled by hardware instruments. DSP System Toolbox™ includes the Spectrum Analyzer software component—one in a set of multichannel streaming scopes.
With spectrum analyzer, engineers visualize, measure, and analyze the frequency domain characteristic of evolving multichannel signals or streaming data in real-time during simulation in MATLAB® or Simulink®.
The spectrum analyzer software computes and displays the spectrum, power-density spectrum, and spectrogram for variety of signals and data types, including audio, biosignals, communication signals, speech, and streaming data. The user interface, features, and measurements are consistent with conventional hardware-based spectrum analyzers.
The spectrum analyzer software in DSP System Toolbox includes the following measures:
