Abstract This paper introduces the concept of an l 0 -system gain for discrete-time LTI systems. It is shown that the l 0 -gain is characterized by the number of non-zero entries in the impulse response of the system and hence gives a natural extension of the notion of sparsity from signals to systems. With this newly introduced system gain, we give a system theoretic explanation of the sparse closed loop response of l 1 -optimal controlled systems by showing that the l 1 -optimal control problem is the best convex relaxation (in the sense of Lagrangian duality) of an appropriately defined l 0 -optimal control problem.
