DSP Toolbox
The application is built with DSP Toolbox which contains the following assemblies which built with .NET Framework 4.0.
  • CodeArtEng.DspToolbox.dllImplementation for virtual signal generator, Fourier Transform, and digital filters.
  • CodeArtEng.DspToolbox.Controls.dll WinForms control for digital filter, virtual DAQ and virtual signal generator.
