About this app
Calculate and visualize the discrete Fourier transform. Supports DFT, IDFT, FFT.
Read full description
DFT Calculator is the essential learning companion for college students taking Digital Signal Processing (DSP) courses. Use this tool to instantly verify your homework and gain a clear, visual intuition for how signal transforms work. Key Features • Solve with Speed: Instantly compute the Discrete Fourier Transform (DFT), Inverse DFT (IDFT), and the efficient Radix-2 Fast Fourier Transform (FFT). • Intuitive Visualization: Don't just get numbers—see your signal! Explore the output on an interactive stem graph, making it easy to understand magnitude and phase. • Flexible Input: Effortlessly add or remove points with a dynamic list to match any problem from your textbook or assignments. Additional Information • ✅ Free and open source • ✅ No ads • ✅ No tracking Get Involved Check out the source code, report an issue, or contribute! https://github.com/Az-21/dft
