 | Match n Freq 5.11 |  | Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency.
Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay. Minimizing Intersymbol Interference in a read/write channel for disc drives by shaping and slimming an isolated readback pulse was the main objective for writing this program. For more info, see Kost, R. and P. Brubaker; 'Arbitrary equalization with simple LC structures'; IEEE Transactions on Magnetics, Nov. 1981, pp 3346-3348 or visit http://www.digitalcalculus.com/page/785704.
This is a Fortran Calculus demo application. |

  | FC-Win 2.00 | | FC-Win (tm) is a front-end program for Fortran Calculus (tm). The Fortran Calculus (FC) language is for math modeling, simulation, and optimization. FC is based on Automatic Differentiation that simplifies computer code to an absolute minimum; i.e., a mathematical model, constraints, and the objective (function) definition. Minimizing the amount of code allows the user to concentrate on the science or engineering problem at hand and not on the (numerical) process requirements to achieve an optimum solution.
A user can buy a FC 'Card' (at "http://www.digitalCalculus.com/products/RBE FC-ODE") and we'll compile and execute their FC programs for him/her. |

 | Rainbow 5.11 | | Find best Spectral Estimation Method for a Power Spectral Density plot. A menu of 10+ spectral estimators from Steve Kay's textbook 'Modern Spectral Estimation' 1988 is available to choose from. The results differ dramatically from one estimator to another. Plus, varying input parameters and/or number of points may provide discrepancies.
See how zero padding effects your results. Manufacturing companies take note! Some estimators can detect signals 50 to 100 dB from main signal. See documented example! The unwritten rule of '30 dB is okay' (i.e. hidden) is no longer true. |

 | CalcExp 1.2.374 | | CalcExp is designed as an alternative to the system build-in calculators. CalcExp runs on Windows 2K/XP/Vista, MacOsX, Linux, and Solaris. The main features are:
1. All-in-one Calculator:
Can be a good alternative to the system build-in calculators and hand-hold calculators. It makes your calculating faster and safer.
2. Powerful Number formatting:
You have many options to choose for formatting the result number, such as: Locales, Fraction Digits, Scientific Notation, Hexadecimal Displaying, etc, while the windows calculator can't do that for you!
3. Friendly User Interface:
Want it always stand on top? or want hide it as a systray icon? yes, you can do that.
Want unlimited undo/redo when editing the expression? Just press Ctrl+Z/Ctrl+Shift+Z.
Want record an expression, then recall it later? Save it in history list.
4. Skin Changeable:
7 Skins(themes) created by professional artists; the font is clear and easy to read.
5. Web Launch:
revolutionary startup manner: Web Launch. It allows you launch CalcExp in a web browser! With just one click, you can install/launch CalcExp on your computer, whatever you working on Windows, Linux, MacOsX, or Solaris.
6. Easy to Use:
View and Edit the expression directly; Avoid making mistakes to it.
7. Custom Functions:
You can define your own Functions and Constants, and use them later like system build-in functions/constants. It saves time and help you work more efficiently.
8. Fully Tested and Safe:
It has passed more than 1141 test cases to make sure your calculation is safe. It comes with a set of Bug Tracing Mechanism to help find any exceptions in calculating and report them to fix at once. This makes CalcExp become safer and safer.
9. Useful Tools:
A great feature of CalcExp is the useful tools, there are good friends in your work. There are 4 useful tools in CalcExp:Unit Converter, Currency Converter, Statistics Calculator, and Color Converter. |

 | FindGraph 1.931 | | FindGraph is a comprehensive graphing, curve fitting, and digitizing tool. FindGraph offers 12 generic fits, including linear regression, logistic functions, fourier approximation, rationals, neural networks, B-splines and parametric curves least squares approximations, plus a library of over 300 industry-specific 2D formulas. FindGraph uses the Levenberg - Marquardt non-linear algorithm and the Simplex algorithm to fit data. A built-in Wizard helps to apply different curve fits to discover the model that best describes the data. Peak fitting features are included. The latest version includes a feature that applies Singular Spectrum Analysis (SSA) to reconstruct and to forecast data series. The software enables you to smooth, interpolate, apply FFT and Wavelet filters, subtract, differentiate, integrate, transform data and curves, and to apply Procrustes analysis. The program comes with 200 built-in common graphing 2D functions support for polar, Cartesian, and parametric equations. A built-in Wizard helps to digitize the data. The program supports OLE automation and can be built-in to other software applications. |
