Non-uniform signal sampling

Discrete sample representation of continuous signals without a grid

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”).
