Positive approximation processes play an important role in Approximation Theory and appear in a very natural way dealing with approximation of continuous functions, especially one, which requires further qualitative properties such as monotonicity, convexity and shape preservation and so on. In this talk, we discuss the degree of approximation of signals (functions) using various types of summability transforms methods in different spaces. Approximation of functions by positive linear operators using Quantum calculus (q-calculus) will also be highlighted. During this talk, few applications of approximations of functions will also be highlighted.
