	CurvFit | License: Freeware | Price: 0.00 |
	CurvFit (tm) is a curve fitting program for Windows. Lorentzian, Sine, Exponential and Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked and/or valleys data. CurvFit is an example of Calculus programming... ie. minutes to solve, days or years to understand solution and what it implies (e.g. wrong model, sampling rate error, etc.). Helps learn 1) whether math model is good for given data; 2) convergence implies a reasonable solution; 3) how to select new starting initial parameter values. See comments in EX*.? files for ideas on how to converge via solvers. Equation Calculator and Hardcopy Plot prints are now (6/2005) available.

	Match n Freq | License: Shareware | Price: 433 |
	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 This is a Fortran Calculus demo application.

	ODEcalc | License: Freeware | Price: 0.00 |
	ODEcalc for Windows: An Ordinary Differential Equation (ODE) Calculator! State your equation and boundary or initial value conditions and it solves your problem. Plots solution y and derivative ydot versus x. Solves most Boundary Value Problems (BVP) and Initial Value Problems (IVP) for Nth order ODE. ODE may be non-linear, implicit, and any order. Source code included ... it's short! Great teaching tool! Helps students understand difference in BVP and IVP plus their importance in solving practical ODEs. ODE and algebraic system of equations may be solved using the methodology in this demo. Hardcopy prints in Windows is now available. This is a Fortran Calculus demo application.

	Rainbow | License: Freeware | Price: 0.00 |
	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.
