What Is Signal Processing Toolbox?

Perform signal processing, analysis, and algorithm development using Signal Processing Toolbox™. Signal Processing Toolbox provides functions and apps to manage, analyze, preprocess, and extract features from uniformly and nonuniformly sampled signals. The toolbox includes tools for filter design and analysis, resampling, smoothing, detrending, and power spectrum estimation. You can use the Signal Analyzer app to visualize and process signals simultaneously in time, frequency, and time-frequency domains. With the Filter Designer app, you can design and analyze FIR and IIR digital filters. Using toolbox functions and the Signal Feature Extractor app, you can prepare signal datasets for AI model training by engineering features that reduce dimensionality and improve the quality of signals. With the Signal Labeler app, you can annotate signals in time and time-frequency domains to create labeled signal sets for training AI models. The toolbox supports GPU acceleration in addition to C/C++ and CUDA® code generation for desktop prototyping and embedded system deployment.
