In this paper, some sufficient conditions for oscillation of symmetric cellular neural networks with delay (DCNNs) are introduced.These conditions impose constrains on the system of dynamic state equations when the cells are working in linear region 1 ( ) ( ) ( ) 0 x t Hx t A x t , where the coefficients H and 1 A are real 2 2 matrix 2 2 R , R , and 2 1 ( ), ( ) x t x t R are the state vector and its derivative at time t .
