Advanced DSP Module

DADiSP/AdvDSP is a menu-driven, advanced signal processing module that adds classical and parametric PSD estimation, linear prediction, Zoom FFT, Chirp Z transform, digital interpolation and cepstrum routines. Each routine is available through an easy to use dialog box interface or simple command line functions. On-line help and examples are also provided.

Classical PSD Estimation

Classical Power Spectrum Estimation techniques include the standard FFT based PSD, the correlation method and the overlapped Welch method of periodogram averaging. Both the segment length and overlap size can be specified. In addition, coherence, cross-power and transfer function estimates are supported.

Parametric PSD Estimation

Parametric estimation techniques include AR – Autoregressive all pole models, MA – Moving Average all zero models, and ARMA, Parametric PSD generalized pole and zero models. The model coefficients are computed from measured data and the coefficients can be used to estimate the PSD as well as provide time domain linear prediction results.

Digital Interpolation

The effective sample rate of any waveform can be changed using a variety of robust digital interpolation algorithms. Traditional Sinx/x bandlimited interpolation as well as non-integer multiple zero insertion routines are provided. Classical linear and cubic spline interpolation functions are also included.

Advanced FFT Analysis

Zoom FFT AdvDSP can compute a true N point FFT. If the series length is less than the specified FFT size, the series is automatically zero padded. If the FFT size is less than the series length, rather than truncation, the series is time aliased resulting in a properly decimated FFT. The Zoom FFT computes the FFT for a selected frequency range and the Chirp Z transform computes the FFT about a generalized Z plane contour.

Cepstrum Analysis

Both real and complex cepstrum computation is available. Cepstrum analysis simplifies the task of echo identification and cancellation for speech and audio applications.


DADiSP/AdvDSP requires DADiSP 6.0 B14 or higher.

The Next Steps

What do our Customers say about us?

Yet again Origin and OriginPro upholds its foremost status as the best purposeful and all-embracing data analysis and graphing software on the market. Although other software packages exist, few are as straightforward to use, flexible, and high-quality when it comes to performing challenging data analysis or creating publication superior graphs.

Keith J. Stevenson, Professor of Chemistry, The University of Texas at Austin

I have always received excellent support with Bibliographic software from your team. Thanks a lot.

I began using Origin because of its versatility in the varied experimental work that we do, from electrophysiology to clinical studies. I have stayed with Origin because of the high level of statistical expertise and customer service that we get from technical support staff.”

“While skeptical at first, now having switched to Origin I know it will remain my graphing software of choice. Not only does it have an intuitive user interface, but it also has the power to quickly and efficiently complete all of my graphing needs. Origin is the best graphing software available. Period.”
