In this study, tire roundness checking system was designed based on FIR digital iflter. FIR digital iflter was designed using equal ripple approach, the iflter frequency characteristic closely approximated the ideal iflter, and thus it provided good ifltering result. The roundness checking system consisted of mechanical system, automation system, data acquisition system and software system. The mechanical system and automation system offered the function of operations. The data acquisition system and software system provided data acquisition and processing work. This checking system possessed high detection efifciency and precision, suitable for batch testing during the tire production process.
