摘要：

Signal generator is an integral part of the electronic system, determines the system performance. With the rapid development of microelectronics technology and digital integrated circuits, the high-precision signal generators are demanded in the field of various kinds electronic systems. To meet this requirement, this paper discusses that DDS chip AD9912 produced linear frequency modulation is controlled by LPC2138 which is ARM chip and the results are displayed by the touch screen, which also used of setting waveform and frequency.
