基于DDS技术的正弦交流信号源的设计
Design of AC sine-signal source based on DDS
摘要
Abstract
For designing and realizing a kind of sine-signal source which can output power, a design of AC sine-signal source based on DDS which used MCU as cybernetics core and AD9850 as frequency synthesizer is introduced. This AC sine-signal source can produce sine signal, which has stable frequency, the frequency range is l~100 Hz, the magnitude of current is adjustable, has certain drive capability and output power. This product used MCU to write Voltage Control Words (VCW) into the AD603 in order to indirectly control and change the gain of the magnitude of voltage, so as to make the RMS current of AC of the same load adjustable. This method has hewn out a new thought for the improvement of function of the congeneric signal-source products.关键词
