Description: fpga implementation dds and downconversion. DDS technology with frequency switching time is short, high frequency resolution, the frequency stability is high, the output signal frequency and phase can be quickly switched, the output phase can be continuous, and changes to maintain a continuous phase, it is easy to achieve frequency, phase, and amplitude digital control. It is the relative bandwidth, frequency conversion time, phase continuity, and a series of high-resolution and integrated performance indicators far beyond the traditional frequency synthesis. Therefore, in modern electronic systems and equipment design frequency source, especially in the field of communication, direct digital frequency synthesizer is used more widely.
