DDS technology is to produce high precision, fast switching frequency, the output waveform distortion of the preferred technique [7] [8], is a digital control signal with the phase of incremental technology, with high frequency resolution, stability, and can be produce a variety of flexible signal a

DDS technology is produced by a high precision, Fast Fourier frequency, output waveform distortion Small of preferred technology [ 7] [ 8] is a digital control signals, the phase-incremental technology with high frequency resolution, stability, flexibility has a variety of signal strengths.

The DDS technology has the high accuracy, the fast conversion frequency, the output wave shape low distortion first selects technical (7)(8), is one kind with the numerical control signal phase increase technology, has the frequency resolution high, the stability good, may have many kinds of signal

DDS technology produces high precision, rapidly transform frequency, the output waveform distortion of first choice technologies [7][8], is a phase of delta technology with digital control signal, with high frequency resolution, good stability, can have a variety of flexible signal strengths.

DDS to produce high precisely, vary distorted little preference of frequency and output waveform select the technology [7 ] [8 ] for use fast in technology, it is one that use digital phase place increment technology of control signal, have frequency resolution ratio high, fine can produce many kind
