The Design and Simulation of DDS Based on Multisim and C51

Abstract:

In order to facilitate intuitive and understanding of the frequency synthesizer technology, research on direct digital frequency synthesizer by the phase accumulator , waveform storage ROM, the D/ Aconverter and low-pass filter modules .Multisim provides powerful virtual electronic platform, realize DDS synthetic sine wave design and circuit simulation by C51 MCU control center, while providing key code. By adjustingthe reference clock frequency fc, or to adjust the frequency control word K, can be clearly seen of the frequency of the synthesized sine wave will be changed.
