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.
