Finally, the internal and external noise measuring instrument trend of development is discussed.
噪聲測量儀已由一般的聲級計發展到噪聲實時分析儀。
This paper introduces a new statistical method for estimating intermodulating noise.
文章提出的寬帶放大器的互調噪聲的統計分析方法是將互調噪聲看成一個隨機過程，根據隨機過程的統計特性加以分析和處理，這種分析估算方法比傳統的用測量總和諧波失真的方法簡便，且不受問題復雜性的限制。
