Query: Approximation by sampling-type operators in $L_p$-spaces   Approximation properties of the sampling-type quasi-projection operators
$Q_j(f,\varphi, \widetilde{\varphi})$ for functions $f$ from anisotropic Besov
spaces are studied. Error estimates in $L_p$-norm are obtained for a large
class of tempered distributions $\widetilde{\varphi}$ and a large class of
functions $\varphi$ under the assumptions that $\varphi$ has enough decay,
satisfies the Strang-Fix conditions and a compatibility condition with
$\widetilde{\varphi}$. The estimates are given in terms of moduli of smoothness
and best approximations.
