m-Freq -- 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....
FC-Win -- 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 (AD) 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....
Rainbow -- 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 parameter and/or number of points may provide discrepancies.
See how zero padding effects your results. See 50+ dB weak signal detect...
ODEcalc -- 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!
A Fortran Calculus demo appl....
Match n Freq -- 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.
This is a Fortran Calculus demo application....
Heat Transfer -- A Heat Transfer problem is described with equations and shows a Calculus-level language used for solving this two point boundary value problem (BVP). The equations being solved may be ordinary differential equations and/or partial differential equations of any order & degree. Equations maybe nonLinear, implicit, any order, any degree and/or constrained.... กก |
