Dsp for MtxVec is a signal processing add-on package for MtxVec. The entire package is designed with streaming support in mind and runs in single or double precision on real or complex signals taking full advantage of vectorized MtxVec design. Components can be conected in to pipes. The product features over 140 routines not counting overloads and more then 30 components. For full product review check out the on-line help file. DSP for MtxVec was designed to work best with TeeChart Pro. The package includes:

IIR filters: Design of analog or discrete Butterworth, ChebyshevI, ChebyshevII, Elliptic and Bessel filters. Order estimation includes all filter types: lowpass, highpass, bandpass and bandstop. Bilinear and Matched Z transform, Group delay, Frequency transformations in S or Z domain, in zero-pole or state-space form. 


FIR Filters: Design of FIR filters with window method or with remez exchange algorithm. Order estimation of FIR filters. Design of hilbert transformers, differentiators and also integrators. Savitzky-Golay filtering, fast envelope detector. Multi-rate multi-stage half-band FIR filtering support includes: zoom-spectrum component, decimate and interpolate components and a high quality envelope detector. 


Non-linear filters: sample-and-hold, sample-and-decay and median filter.


Spectral analysis: State-of-the-art spectrum analyzer component with ready to use component editor covering: FFT, CZT, Yule-Walker, Burg, Covariance and Modified Covariance spectral estimation, RMS of specified frequency bands, a set of peak interpolation algorithms, a large set of window functions including: Bartlett, Blackman, Chebyshev, CosineTappered, FlatTop, Hamming, Hanning and Kaiser window; sophisticated peak selection and peak tracking methods, phase unwrapping algorithm, dedicated components for bispectrum, bicoherence, coherence and transfer function estimation with real-time capability. Real cepstrum, complex cepstrum and inverse complex cepstrum, Spectral statistics: Noise floor, SFDR, THD, THDN, SINAD, RMS, SNR...


Linear systems: find zeros of a linear system, convert between state-space, zero-pole and numerator-denominator forms of the transfer function. 


Other components: signal generator component with ready to use component editor offers stack-based vectorized function evaluation with many built-in functions. Audio recording and playback components with monitor function and extensive support for triggers. Ready to use component editor for filtering component covers design of nearly all included filters. Components for streaming (read/write) different file formats. 


TeeChart Pro (v5 and v6) support includes: two new TChart components to allow visual connection of the signal processing pipes to charts, two new TChartSeries for faster drawing and 3 additional TeeTools components to help with peak marking and axis scaling.


Together with MtxVec the following functions/operations are provided: frequency response of analog and discrete filters, fast 1D and 2D convolution, fast autocorrelation and cross-correlation, deconvolution, 1D and 2D filtering, zero phase IIR filtering, interpolated FIR filters, DCT and inverse DCT, Geortzel algorithm and forward and inverse FFT for all combinations of real/complex source and destination, random number generators and more...
