1. For analog multiplier , the basic principles were analyzed and input , output circuits were designed
   對于模擬乘法器,分析了其工作原理,并設(shè)計其輸入輸出級使其適合設(shè)計要求。
2. Based on the coherent modulation model , doppler information is obtained by using ad633 analog multiplier and active low pass filter ; 3
   以相干檢波一般模型為基礎(chǔ)，采用ad633模擬乘法器和有源低通濾波器實現(xiàn)了對多卜勒信息的提??； 3
3. Many international companies have put their pfc chips on the markets , such as mc33262 , mc34262 , l6561 , l6562 , ml4812 etc . in this paper , we studied on critical current mode active power factor correction technology , and did a detailed analysis and design on voltage reference circuit and analog multiplier circuit
   國際上已經(jīng)出現(xiàn)了一些有源功率因數(shù)校正芯片,如onsemi公司的mc33262 、 mc34262 , st公司的l6561 、 l6562 , microlinear公司的ml4812等產(chǎn)品。本文研究了有源功率因數(shù)校正技術(shù)中的臨界導(dǎo)通模式的基本原理,并對其中的電壓基準(zhǔn)源和模擬乘法器做了詳細(xì)的分析和設(shè)計。
4. At present , the typic harmful current detection methods are the fast fourier transform algorithm in frequency domain and methods based on the instantaneous reactive power theory , these methods all require some transform and quick , real - time calculating , so high precision analog multipliers or high speed dsp chip with fast a / d are needed , this results in complex circuit and high cost ， which have restricted the development of apf
   目前畸變電流檢測常用的方法有頻域法的fft和基于瞬時無功理論的畸變電流檢測法。這些方法均有一定的變換，需要快速、實時運(yùn)算，因此必須使用高速的數(shù)字微處理器和高性能a / d轉(zhuǎn)換器，這必將大大提高系統(tǒng)成本，使得電路結(jié)構(gòu)復(fù)雜，在一定程度上限制了有源濾波器的發(fā)展。
5. It's difficult to find analog multiplier in a sentence. 用analog multiplier造句挺難的
