Abstract
In this paper we obtain the saturation order, a strong localization result and local saturation results in the approximation of continuous positive functions by the truncated max-product sampling operators based on sinc (Wittaker-type) and Fejér-type kernels. The localization-type results obtained present important potential applications in signal theory.
