摘要
对比分析几种常见抑制杂散的方法。针对DDS信号大量的杂散、相位截断、幅度量化等问题,提出了一种新的均和加扰方法,并应用在DDS信号源设计中,对抑制杂散信号非常有效。
Several methods of reducing spurious signals are analyzed.To resolve spurious signals,phase truncation and amplitude quantization of DDS signal,a new method called Balancing scrambling technology is presented.This method is applied to the design of DDS signal source and is very effective for the suppression of spurious signals.
