This paper presents the hardware structure, working principle and software flow chart of the programmable signal generator and frequency detector device, which uses TMS320LF2407 as core.

Data Generator can generate very complicated digital signals. It can be used as programmable data signal source in the fields of communication, radar, navigation, space navigation, and so on.

In the basis of pulse Doppler digital fuze, the programmable pulse generator, digital receiver and digital signal processor are designed in detail.
