Signal Processing Toolbox
Perform signal processing, analysis, and algorithm development
Signal Processing Toolbox™ provides industry-standard algorithms and apps for analog and digital signal processing (DSP). You can use the toolbox to visualize signals in time and frequency domains, compute FFTs for spectral analysis, design FIR and IIR filters, and implement convolution, modulation, resampling, and other signal processing techniques. Algorithms in the toolbox can be used as a basis for developing custom algorithms for audio and speech processing, instrumentation, and baseband wireless communications.
