This submission will now wait until an administrator reviews it and chooses whether to add it to the directory. If you would like to become an admin, then visit the directory mailing list and introduce yourself.

Admins, either this page has been processed already, or someone made a request to update an existing page. See what's different. (Admins may also edit that page.)

Admins, when you are done incorporating any needed changes from this page into a main entry, please edit this page and change the following text from: |Finished review=No to: |Finished review=yes. This helps keep submissions organized. (Note that doing this isn't what adds the entry to the directory.)

Name C-Graph
Short description GNU C-Graph is an interactive package that demonstrates the mathematical operation of convolution. The package is written in Fortran. " C-Graph" is an abbreviation for "Convolution Graph".
Full description GNU C-Graph is a tool for visualizing the mathematical operation of convolution underlying natural phenomena susceptible to analysis in terms of engineering signals and systems theory. "C-Graph" is an abbreviation for "Convolution Graph". The package is derived from the BSc. Honours dissertation in Electrical Engineering "Interactive Computer Package Demonstrating: Sampling Convolution and the FFT", Adrienne Gaye Thompson, University of Aberdeen (1983). The package computes the linear convolution of two signals in the time domain then compares their circular convolution by demonstrating the convolution theorem. Each signal is modelled by a register of discrete values simulating samples of a signal, and the discrete Fourier transform (DFT) computed by means of the Fast Fourier Transform (FFT). GNU C-Graph is interactive, prompting the user to enter character or numerical values from the keyboard, dispensing with the learning curve for writing code. The software will be useful to students of signals and systems theory. C-Graph is written in contemporary Fortran. You can find pre-GNU development versions at: <http://codeartnow.com/code/download/c-graph-1/c-graph-version-2-preview>. Adrienne Gaye Thompson is the sole author of GNU C-Graph.
