Two Kinds of Control Circuit Design For Direct Digital Frequency Synthesis Based on FPGA
Yue Fu · 2007
This paper introduces two kinds of plans with control circuit what achieve direct digital frequency synthesis based on FPGA,using phase accumulator and proportion multiplication. The paper introduces their principles and how the design becomes true. The control circuits combine VHDL with principle chart. In EPF10K of FPGA the design realizes. DDS technique combine with single chip can achieve producing signal equipment which is convenient,flexible and accurate.
