We provide sufficient density condition for a set of nonuniform samples to give rise to a set of sampling for multivariate bandlimited functions when the measurements consist of pointwise evaluations of a function and its first k derivatives. Along with explicit estimates of corresponding frame bounds, we derive the explicit density bound and show that, as k increases, it grows linearly in $$k+1$$k+1 with the constant of proportionality $$1/\mathrm {e}$$1/e. Seeking larger gap conditions, we… CONTINUE READING
