Signal sampling without equal bins and thus a simple Nyquist Theorem. It turns out that this is not fatal for many signals.

Reviews in BaSt10, PiPe04, Eng07, Unse00.

This is sometimes extended to include signal reconstructions with
*uncertain* sampling times.

For FFT of unevenly sampled points, you can try the Non uniform FFT (“NuFFT”).

Implementations:
