摘要
采用直接数字频率合成技术(DDS),通过数字控制相位信号的增量在FPGA中实现频率可调的信号发生器,所产生的信号不仅幅度频率灵活可调,并具有频率分辨率高、切换速度快、相位噪声低等优点,因而该系统设计在相关的科研实践中具有重要意义。
A signal generator is designed with the direct digital frequence synthesis（DDS） technology, through the digital controlling the increment of signal phase and a FPGA system.The signal of this generator has many advantages such as convenience for changing magnitude and frequency,high resolution,high frequency changing speed,reducing phase noise.The signal generator has been used in all kinds of applications.
