Coarse quantization for random interleaved sampling of bandlimited signals
ESAIM: Mathematical Modelling and Numerical Analysis , Tome 46 (2012) no. 3, pp. 605-618.

The compatibility of unsynchronized interleaved uniform sampling with Sigma-Delta analog-to-digital conversion is investigated. Let f be a bandlimited signal that is sampled on a collection of N interleaved grids  {kT + Tn} k ∈ Z with offsets \hbox{{T n } n=1 N ⊂[0,T]} { T n } n = 1 N ⊂ [ 0 ,T ] . If the offsets Tn are chosen independently and uniformly at random from  [0,T]  and if the sample values of f are quantized with a first order Sigma-Delta algorithm, then with high probability the quantization error \hbox{|f(t)-f ˜(t)|} | f ( t ) - 􏽥 f ( t ) | is at most of order N-1log N.
