The system is the wave generator which controls by the monolithic integrated circuit. The wave generator took one kind of test facility large-scale, the ultra large scale integrated circuit chip test and in the digital system design obtains the widespread application. This design system may realize the standard wave pattern occurrence function, including the peak-to-peak value, the frequency function hypothesis. In order to fully realizes these functions, and expanded the keyboard entry function, uses in to adjust the output signal.
This system mainly realizes regarding the wave peak-to-peak value and the frequency adjustment by software, First uses MAX038 to build a profile to have the electric circuit, Then controls this wave with the monolithic integrated circuit, also the read-in user according to own need the data which inputs by the keyboard, by the software realization wave change, realizes the D/A transformation by DAC0832. This generator output has the sine wave, the triangle wave, the square-wave three kind of waveform, the output signal frequency in the scope is in the 1Hz~1KHz scope, greatest peak-to-peak value 3V carries on the adjustment through the program control method, the output is stable, the degree of distortion is very small.
Key words: mcu wave generator max038
