For single-channel FFT operations, the .NET library provides routines for calculating the spectrum, auto spectrum and Power Spectral Density (PSD). The functionality for two-channel FFT operations includes frequency response, cross spectrum and coherence functions.
In addition to flexible windowing and averaging options (Hamming, Hanning, Blackman, Bartlett, etc.), the object-oriented class library also features routines for calculating typical signal metrics, including Input Below Full Scale (IBF), Total Harmonic Distortion (THD), Signal to Noise Ratio (SNR) and many more.
The applications developed with the .NET Signal Processing Library can be distributed royalty-free.
