KW - Meyer-König and Zeller-Durrmeyer type operator, moduli of smoothness, $K$-functional, strong converse inequality, Hölder's inequality.
AB - <p style="text-align: justify;">In this paper we give a strong converse inequality of type B in terms of
unified $K$-functional $K^α_λ (f, t^2) (0 ≤ λ ≤ 1, 0 &lt; α &lt; 2)$ for the Meyer-König and
Zeller-Durrmeyer type operators.</p>
