Suppose that you have graduated from College with an engineering degree and you start working for a local contracting company. For your first job, you are asked to design a circuit to duplicate the input-output response for small-amplitude inputs of a given system. This system has an input port and an output port. You are told that the system is probably linear for small-amplitude signals. The given system has no built-in batteries, and you are able to measure with an oscilloscope a zero-state response that is not zero even when the input is grounded. Can the system be linear?
