  11. For the application of direct broadcast satellite ( dbs ), a ku - band high image rejection broadband mixer is designed using ads. it appears predominant performances when compared with common single balanced mixer

    針對衛星電視直播接收系統,用ads設計了一個寬頻帶、高鏡像抑制度、低噪聲的ku波段鏡像抑制混頻器,並同普通平衡混頻器進行了對比分析,顯示了其優越的性能。
  12. This ku - band three channel receiver consists of spst modules, lna modules and image rejection mixer modules. these modules were designed and tested separately, then were assembled to the whole receiver. all the circuits were designed with small - sized devices so as to reduce the total size of the receiver. and the noise figure was considerably reduced because of the image rejection mixer

    另外,由於採用了鏡像抑制混頻器,從而使整機噪聲系數大為降低。在設計方法上,本文採用了先進的微波電路設計軟體ansoftserenade對所有的電路和系統進行設計、優化和模擬,大大的縮短設計周期,提高設計效率。

    此外你會慢慢變得隨波逐流缺乏主見,隨之產生前面章節討論的自暴自棄心理。
  14. In the “ abstract series ”, there is a decisive rejection of recognisable imagery in favour of expression, whilst in the “ life series ”, we cannot say that there are pieces that do not have morally loaded themes : the image transcends the transitory and local interest, being concerned with the themes of social realism and urban existance

    在「抽象系列"里,畫家堅定地拒絕可識別的形象表達,而在」生命系列「里,我們不能說裏面有沒有精神承載的主題:圖像超越瞬間和地方興趣,與社會現實主義和都市生活的題材相關聯。
