Signal Processing Toolkit

Interactive signal plotter and learning platform

The Signal Processing Toolkit (SPT) is an interactive, FAU‑developed platform for continuous‑ and discrete‑time signal exploration. Use it to plot your signals, perform convolution, explore transforms and learn signal processing concepts through hands‑on modules.
