Description: interactive visualization tool for the convolution theorem
GNU C-Graph is a novel tool for visualizing the mathematical operation
of convolution. "C-Graph" is an abbreviation for "Convolution Graph".
A game changer, C-Graph -- the de facto tool for visualizing the convolution
theorem in universities worldwide -- is invaluable for lecture demonstrations
and lab work in the teaching of signals and systems, as well as other courses
featuring convolution. GNU C-Graph is widely used across industries that
utilize signal processing techniques for design, test, and development:
telecommunications, instrumentation and control, manufacturing, automotive,
aviation and aerospace, medical devices, and others. This nifty package
seamlessly generates publication quality graphics for papers, lecture
demonstrations, and other professional presentations.
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. A Texinfo manual provides sample sessions and an overview of
the convolution theorem. C-Graph 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).
Select, Transform, Visualize : GNU C-Graph makes visualizing convolution easy
Uploading this package will close the associated RFP bug #694088 filed in 2012.
