-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2013-1120 2013-01-20 02:12:15 --------------------------------------------------------------------------------
Name : c-graph Product : Fedora 18 Version : 2.0 Release : 3.fc18 URL : http://www.gnu.org/software/c-graph Summary : A tool for visualizing convolution Description : GNU C-Graph is a novel 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. Honors 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 modeled 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 is an excellent tool for lecture demonstrations and lab work in the teaching of signals and systems theory.
C-Graph is written in Fortran. Adrienne Gaye Thompson is the sole author of GNU C-Graph.
