This design uses TMS320F2808 DSP chip, produced a digital audio frequency sweep generator, capable of measuring an unknown network audio amplitude-frequency characteristics within. The system has good scalability, software adjustable key system parameters, and can be achieved through algorithm design phase frequency characteristics are measured, while compact and flexible, with a real-time, high accuracy. Users can through the PC, convenient and flexible user-friendly interface to control the entire system, view data and observation test curve.
