Transmitter has a high frequency stability and big FM deviation and can also operate under the changing of power supply voltage in the range of. 30%.

其发射机频率稳定度高，调制频偏大，在电源电压变化约30%的条件下亦能稳定工作。

Such problems as the attenuation of DC elements and Sine waveform, voltage sag and frequency deviation should be taken into account in order to analyze the transient process in the power system.

要分析电网的暂态特性，还必须考虑衰减直流分量和衰减正弦波，以及电压缺口和频率偏移等问题。
