carrier-frequency pulse
常见例句
- This paper presents a frequency comparison method between two sites by colour sub-carrier pulse, and some experiment results are given.
本文叙述一种直接利用彩色副载波脉冲进行两地频率比对的方法，并给出某些比对试验结果。 - But to the CW pulse signal with changing carrier wave frequency, common filter cannot achieve narrowband filter, whereas broadband filter cannot reach the request of the signal-noise ratio.
可是，对于载波频率不断变化的CW脉冲信号，普通的滤波器难以实现窄带跟踪滤波，而宽带滤波又不能达到提高信噪比的要求。 返回 carrier-frequency pulse
