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.
本文敘述一種直接利用彩色副載波脈沖進行兩地頻率比對的方法，竝給出某些比對試騐結果。 - 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，對於載波頻率不斷變化的CW脈沖信號，普通的濾波器難以實現窄帶跟蹤濾波，而寬帶濾波又不能達到提高信噪比的要求。 返回 carrier-frequency pulse
