摘要
介绍采用直接数字合成 (DDS)技术来合成任意波形的方法。通过此方法可以方便的合成任意波形 ,并且波形失真度小 ,频带宽 ,频率调节精度高。
Whole frequency range is divided into several frequency range, and the arbitrary waveform is synthesized by using DDS on everyone frequency range. We can conveniently synthesis arbitrary waveform, and degree of distortion is low, frequency range is wide, the precision of frequency regulator is high.
