Description: In this paper, the use of DDS as a signal of the whole core of the device function signal generator digital design, according to the type of output signal waveform can be set, the output signal amplitude and frequency can be CNC, such as output frequency width requirements, selection of the United States A/D Company the AD9850 chip, and AD9850 single-chip control and handling of 32-bit frequency control word, and then amplified by the increase to a Digital Potentiometers Digital decay at the core network, in order to achieve a signal amplitude, frequency, type and output Options such as all-digital control
