Research and Application of Digital Frequency-multiplier Based on DDS
Ju Wu · Microcomputer Information · 2009
Has realized the digital-frequency-multiplication of periodic Signal based on the DDS and equal-precision frequency mea- surement.The MCU determines the input signal frequency and calculates the frequency-multiplication-signal's frequency according to the frequency multiplication number,and produces the frequency-multiplication-signal using DDS.The frequency multiplication principle and accuracy are analyzed,and has confirmed the design accuracy through the experiment.
