lighter phase 中文意思是什麼
lighter phase
解釋
輕相-
Frequency source is widely used in today ' s electronic equipment and even refered as " a heart " of many electronic systems. the frequency synthesizer with a lot of channels and high frequency stability by means of theory of phase locking has almost been a necessary component in the modern electronic systems such as telecommunication, radar and electronic countermeasure. the phase - locked frequency synthesizer can be generally divided into two kinds : one is digital phase locked frequency synthesizer, the other is analog sampling phase locked frequency synthesizer. compared with the prior, the latter has many merits such as lower phase noise, samller volume, lighter weight and lower power consumption and has a wide foreground in the equipments of microwave band
利用鎖相原理來獲得波道數目眾多、頻率穩定度很高的頻率合成器，幾乎已成為現代通信、雷達和電子對抗等電子系統不可缺少的組成部分。鎖相式頻率合成器一般分為數字鎖相頻率合成器和模擬取樣鎖相頻率合成器兩類。取樣鎖相頻率合成器與數字鎖相頻率合成器相比，具有相位噪聲低、體積小、重量輕和功耗低等優點，尤其在微波波段的電子設備中，具有廣闊的應用前景。
