| contents | The concept of mixed norm spaces has emerged as a significant interest in fields such as harmonic analysis. In addition, the problem of function approximation through sampling series has been particularly noteworthy in the realm of approximation theory. This paper aims to address both these aspects. Here we deal with the problem of function approximation in diverse mixed norm function spaces. We utilise the family of Kantorovich type sampling operators as approximator for the functions in mixed norm Lebesgue space, and mixed norm Orlicz space. The Orlicz spaces are well-known as a generalized family that encompasses many significant function spaces. We establish the boundedness of the family of generalized as well as Kantorovich type sampling operators within the framework of these mixed norm spaces.Further, we study the approximation properties of Kantorovich-type sampling operators in both mixed norm Lebesgue and Orlicz spaces. At the end, we discuss a few examples of suitable kernel involved in the discussed approximation procedure. |
