SPT - The Signal Processing Toolbox for O-Matrix


Signal Processing Analysis, Algorithm Development, and Solution Visualization

SPT, The Signal Processing Toolbox for O-Matrix, provides a broad extensible set of functions and utilities which expand the capabilities of O-Matrix in the area of digital signal processing. Built on the high-performance and flexibility of O-Matrix, the toolbox has tools for algorithm development, data analysis, and visual presentation.

SPT contains functions for performing many operations common to the area of digital signal processing. Linear FIR filter functions create several types of filters including lowpass, highpass, bandpass, bandstop, Hilbert transformers, and pulse-shaping filters (raised cosine types commonly used in digital communications systems). Similar capabilities are provided for IIR filters. Various signal generators such as random bit generators, noise generators, simple waveform generators, common carrier modulation waveforms such as AM, FM, PM, and general quadrature modulation are included for test and simulation purposes. Spectral smoothing, histogramming, data manipulation, and various mathematical functions add to the powerful O-Matrix environment.
