FFT Werk is a powerful virtual spectrum analyzer tool that allows digital signal processing and FFT conversion of time domain signal to frequency spectrum (and vice versa).

FFT Werk includes fast and convenient tools for signal analysis and different methods for data smoothing, interpolation and windowing:

• Interpolation (Linear, Quadratic, Cubic Spline)
• Smoothing (Exponential, Savitzky-Golay, Binomial)
• Windowing (Hann, Flat Top, Kaiser-Bessel, Blackman-Harris, Triangle, Hamming, Blackman, Nuttall, Blackman-Nuttall)
