A Complex Multi-frequency Synthesis Technology Applied to Electromagnetic Detecting Source 电磁探测场源的复杂多频点时钟设计
We design and complete a multi-frequency source current module, applying the Direct Digital Synthesis ( DDS ) technology. We use the DSP chip as our controller and the frequency, phase and amplitude of the signal are all programmable and adjustable. 设计并完成了多频恒流源模块,采用了直接数字合成(Directdigitalsynthesis,DDS)技术,应用数字信号处理器(DSP)作为控制器,实现了频率、相位和幅值均动态可调。
