This paper focuses on the stability analysis of a discrete-time linear system with an interval-like time-varying delay in the state. A novel inequality for finite-sum is first established. The new inequality together with convex combination technique results in a novel delay-dependent stability criterion, which has been proven theoretically to be less conservative than some existing ones reported in the literature. Two numerical examples are given to show the validity of the proposed method.
