  1. The in - depth analysis of the noise in gilbert mixer including parasitical capacitors, in which the mixer and lna have been connected together and the noise figure of mixer can be expressed explicitly as that of lna

    回在包括寄生電容的情況下，對雙差分對混頻器（ gilbertmixer ）的噪聲性能做了深入分析，把混頻器和低噪放聯系在一起，可像低噪放一樣，直觀的表達混頻器的噪聲系數。
  2. We illustrate the wavelet package analysis that can obtain the time - frequency distribution figure of noise signal, which can be used to define gray - image. through image - average, we can get the standard time - frequency distribution images of different main bearing gap. based on that, a main bearing wear fault diagnosis model using image matching is set up

    然後對圖像進行平均，得到主軸承在不同間隙狀態下的「標準」時頻分布圖，建立了柴油機主軸承間隙圖像匹配的故障診斷模型，匹配時所用的參數為兩幅圖像之間的歐氏距離。
  3. How to reduce noise figure of operational amplifier are studied in this paper. through design of a low - noise opa, introduce low - noise design of the input stage in detail. and with the analysis of computer, suitable sizes of the input apparatus are choosed. at last, by simmulation and verification on this opa, the result is satisfied

    研究了如何從電路結構上減少運算放大器的噪聲，以一種低噪聲運放為例，著重介紹輸入級設計，並藉助計算機分析選擇合適的輸入器件尺寸，最後通過對運放噪聲的模擬驗證，得到了滿意的結果。
  4. Use eda software to simulate the optimization z sand z l in pa designation. 3. theoretically deep analysis is made which is about the method of lna design, analysis the affect of noise figure and input vswr to the system sensitivity and the contradiction between the two parameter

    3 .從理論上低噪放設計方法進行深入的研究，系統的分析低噪放的輸入駐波比和噪聲系數這兩項指標對接收機系統靈敏度的影響以及兩者之間的矛盾。
  5. And then lodge a design method of lna which can get low noise figure and low input vswr simultaneity. 4. introduced the method of yield analysis and optimize to the lna design, by this method, difficulty of debugging was reduced

    進而從理論上提出一種能較好的處理好兩者之間矛盾的低噪放設計方法，並運用到實際產品的研製過程中; 4 .將合格率分析和優化的方法引入到低噪聲放大器的設計中，大大的降低電路的調試難度，設計出有較高的一次通過率的產品。
