The signal generator has the microcontroller AT89S52 and D/A converter DAC0832 as the hardcore.Controlled by the AT89S52,DAC0832 produces the required current.Then the operational amplifier LF393 linearly converts the current to a 0~5 V voltage.Through the control of the program,the system can produce a series of regular waves.The system has the advantages of high precision,strong anti-interference,stable performance,easy upgrade and high practical value.

Key words: AT89S52;DAC0832;signal generator;D/A conversion
