Follow these instructions in order to run this app:
- 1. Downloaded this application in your PC.
- 2. Enter in our file manager https://www.onworks.net/myfiles.php?username=XXXXX with the username that you want.
- 3. Upload this application in such filemanager.
- 4. Start any OS OnWorks online emulator from this website, but better Windows online emulator.
- 5. From the OnWorks Windows OS you have just started, goto our file manager https://www.onworks.net/myfiles.php?username=XXXXX with the username that you want.
- 6. Download the application and install it.
- 7. Download Wine from your Linux distributions software repositories. Once installed, you can then double-click the app to run them with Wine. You can also try PlayOnLinux, a fancy interface over Wine that will help you install popular Windows programs and games.
Wine is a way to run Windows software on Linux, but with no Windows required. Wine is an open-source Windows compatibility layer that can run Windows programs directly on any Linux desktop. Essentially, Wine is trying to re-implement enough of Windows from scratch so that it can run all those Windows applications without actually needing Windows.
Jean-Baptiste Fourier (JB)
JB is a signal processing lab. It offers many easy to use commands to perform various signal analysis and simulation operations in a simple environment and on an intuitive manner. With JB, you can generate many signals (sine, square, exponential, sinc, triangle, noise, windows…) and perform many calculations on it (Fourier transform, (de)convolution, (cross and auto)correlation, delays filters, z transform….). JB is intended for training purpose. With it, you can teach or learn and experiment yourself with the basic concepts of signal processing. You can work on internally generated signals, or on externally acquired signals via import and export functions. You can expand JB via "user tasks" written using the high level and easy to use Python programming language.
- Synthetic waveform generator: sinus, square & rectange, triangle, sawtooth, gaussian and uniform noise, sinc, exponetial, window, dirac impulse, heaviside step, AM FM & chirp modulated sine.
- Hann, Hamming, Bartlett, Blackman, Blackman-Harris, Flattop, Welch & Kaiser windows
- Uniform and gaussian noise generator.
- Classic DSP operations: FFT, Convolation, Correlation, IIR & FIR filters...
- See full list of features on the home page.
This is an application that can also be fetched from https://sourceforge.net/projects/jbj/. It has been hosted in OnWorks in order to be run online in an easiest way from one of our free Operative Systems.
