Portable ecg data acquisition has the functions of ecg signal amplification and pre - data processing 完成心電信號的采集,放大, a d轉(zhuǎn)換,濾波等功能。
Some commercial odor sensors and their performance are introduced and compared . then the three key parts of electronic nose : sensors array , signal amplification circuit and ad board are also introduced 介紹了本課題中采用的電子鼻硬件系統(tǒng)的三個組成部分傳感器陣列、信號調(diào)理電路和數(shù)據(jù)采集卡。
The translocation of gq has been proposed as one of the molecular mechanisms to control photoreceptor sensitivity . its role is molecular switch and signal amplification in photo - electro transduction Gq蛋白亞基的移位被認為是控制感光細胞光敏性的重要分子機制之一,在光電傳導(dǎo)中起分子開關(guān)和信號放大作用。
The system consists of five units : ecg monitor , microcontroller and a / d converter , home network gateway and medical information management . ecg monitor has the function of ecg signal amplification 系統(tǒng)由五部分組成:心電檢測單元,單片機控制及a d轉(zhuǎn)換單元,家庭無線傳輸單元,家庭嵌入式網(wǎng)關(guān)及醫(yī)院數(shù)據(jù)管理單元。
4 . pulse signal is researched when amplified by edfa . for signal with a frequency of 10 khz , the gain is about 3db higher than sequence signal amplification , but in time domain , aberrance occurred with the amplified signal 4 .建立了edfa非穩(wěn)態(tài)放大模型,對頻率為10khz的脈沖信號進行了實驗分析,結(jié)果表明,其小信號增益比連續(xù)光放大提高了3db ,但輸出脈沖存在畸變。
