output wave shape meaning in Chinese

输出波形

At last we introduce the realization of all the parts , the problem in the circuit design and the measured data . the results show that the designed system has met the requirement . in this dissertation , direct digital synthesis technology has been used in the phase - locked frequency synthesizer , which can make full use of the characteristics of direct digital synthesis technology such as flexible output wave shape and continuous
本课题将直接数字式合成技术用于锁相频率合成器中,该方法将直接数字合成的特点,如输出波形灵活且相位连续、频率稳定度高、输出频率分辨率高、频率转换速度快、输出相位噪声低、集成度高、功耗低、体积小等与锁相环路的频带宽、工作频率高、频谱质量好等优点有机的结合起来,从而在宽带的条件下实现了比较好的杂散性能和相噪。
