A Novel Method to Calculate Frequency Control Word of Direct Digital Synthesizer

Abstract:

Article Preview

When designing signal generator with adjustable frequency based on direct digital synthesis technology (DDS), it is very important to calculate the frequency control word. To address the shortcoming of large computation, low efficiency of frequency setting, more storage space occupied or significant cumulative errors of frequency setting when calculating frequency control word with traditional methods, a novel calculation way for frequency control word is researched in this paper. This new method does not need large computation and more space and simultaneously it can decrease the error greatly, which plays an important role in improving the frequency setting speed and precision in signal generator.
