摘要： PURPOSE:To speed up frequency switching, to control phase and to attain the synthesizing of high frequencies, by producing plural AC signals different in phase by a common frequency, selecting a signal at each designating time to form a time series signal. CONSTITUTION:When outputs signals of a signal generator 1 11-1N are fed with N-waves of AC signals sin(omegact)-sin[omegact+(N-1)theta] shifted in phase theta, the signal is outputted to an output terminal 23 in the phase shift order by theta. The sampling is done synchronizing with the input signal and the phase is shifted by theta at each time Ts as shown in Figure, then the component of angular frequency omegac+theta/Ts is included. Thus, the frequency different from the reference frequency is synthesized, and the frequency switching is attained by having only to select an input terminal, then it is executed in a short time and the phase control is also attained by changing the input terminal.
摘要翻译：目的：为了加快频率切换，控制相位和达到合成高频，通过产生相位不同的多个交流信号，通过共同频率，在每个指定时间选择信号，形成时间序列信号。构成：当以信号发生器1111-1N的输出信号馈送有相位θ移位的交流信号sin（ωgact）-sin [ωgact+（N-1）theta]的N波时，该信号被输出到输出端 23的相移顺序为θ。采样与输入信号同步完成，并且如图所示，在每个时间Ts，相位偏移θ，则包括角频率ωgac+θ/ Ts的分量。因此，与参考频率不同的频率被合成，并且通过仅选择输入端子来实现频率切换，然后在短时间内执行，并且还可以通过改变输入端子来实现相位控制。
