【Abstract】 This article lists the theory of IIR filter and how to design it. It analyzed how the Serial Interface of TMS320C5402 work and the specialty of TLC320AC01. Then list a link between C5402 and AC01,so that the system can both process digital signals and analog signals. In the end,it provides the material way of system design and implement IIR filter base on CCS and DES5402PP board.更多还原
