基于DSP和DDS技术相位及频率严格可调的多路同步信号发生器
DSP and DDS Based Multiplex Synchronous Signals Source with Frequency and Phase Adjustable
摘要
Abstract
The signal generator based on a DSP chip TMS320F2812 and multiple DDS chips AD9833 can generate multiple signals with strictly adjustable frequency and phase. This circuit is used in a rotation drive circuit of elec-tromagnet levitation micromotor with stator embedded. The control words are compiled by C and loaded serially to adjust frequency and phase difference by software. The generated signals are stable and accurate with high resolution frequency and accurate phase difference.关键词
