Electronic circuits is now the design in the application of the necessary equipment. The design of the main purpose is to learn revivification function of the generators works, a low frequency function of the generators. in this design could not only allow me to the principle functions of programme,there is more, but also for a more monolithic integrated circuits to learn. Monolithic integrated circuits there are many varieties, and the production function of the generators, the design is AT89c51 monolithic integrated circuits to the selection of a module dac0832 the chips, and supported by the simulation circuits, and devised a function of the signal based on at89c51 monolithic integrated circuits generators. The design includes monolithic integrated circuits to the system design, and D/A the module for the design, the keyboard control module of the design and LCD modules display design. One of D/A the modules including two dollars and op07 dac0832 the discharge of the D/A, the chip is the D/A chip of the voltage and the first piece of D/A chips 5v reference by 2. the voltage mc1403 chip of the output to provide; keyboard control in three key to select the type and frequency, wave of value displays module lcd1602;is used to indicate the type and frequency and wave be; Eventually will be designed to function of the generators output meet on oscilloscope, in the wave is varied in the practical output. The design of the will to achieve the desired results can be achieved step 3 1v voltage and waves to any regulation of free and lcd1602 than on the type of signal wave, voltage and frequency, and may, by the wave is varied to observe the output. 【Key words
