It will give patients treatment by means of the amplified amplitude modulating wave current that can be obtained form medium frequency amplitude modulated by the low frequency pulse signal.
它将有关低频脉冲信号对中频调幅后，利用被放大的调幅波电流对人体进行治疗。
2
And it has functions of outputting different analog signals, impulse signal with different frequency, amplitude and different waveform.
同时具有输出各种模拟信号、不同频率和幅值的脉冲信号及各种波形信号的信号源功能。
3
The significant factors which exert an influence on instantaneous fluctuation of motor current are in sequence :Vari-speed waveform, vari-speed amplitude and vari-speed frequency.
