發(fā)音:   用"analog sample"造句

例句與用法

  1. The hardware of system is the data acquisition equipment ( daq ) , daq includes three main functional modules : fpga , analog sampling and lcd controlling
    系統(tǒng)的硬件部分是數(shù)據(jù)采集卡,數(shù)據(jù)采集卡在功能上分為fpga ,模擬采樣和液晶驅(qū)動(dòng)及控制三個(gè)組成部分。
  2. Frequency source is widely used in today ' s electronic equipment and even refered as " a heart " of many electronic systems . the frequency synthesizer with a lot of channels and high frequency stability by means of theory of phase locking has almost been a necessary component in the modern electronic systems such as telecommunication , radar and electronic countermeasure . the phase - locked frequency synthesizer can be generally divided into two kinds : one is digital phase locked frequency synthesizer , the other is analog sampling phase locked frequency synthesizer . compared with the prior , the latter has many merits such as lower phase noise , samller volume , lighter weight and lower power consumption and has a wide foreground in the equipments of microwave band
    利用鎖相原理來獲得波道數(shù)目眾多、頻率穩(wěn)定度很高的頻率合成器,幾乎已成為現(xiàn)代通信、雷達(dá)和電子對抗等電子系統(tǒng)不可缺少的組成部分。鎖相式頻率合成器一般分為數(shù)字鎖相頻率合成器和模擬取樣鎖相頻率合成器兩類。取樣鎖相頻率合成器與數(shù)字鎖相頻率合成器相比,具有相位噪聲低、體積小、重量輕和功耗低等優(yōu)點(diǎn),尤其在微波波段的電子設(shè)備中,具有廣闊的應(yīng)用前景。
  3. For the measurement of analog signals such as voltage and current of astg , a filter card for pre - disposing is designed , in order to improve real - time performance , algorithms for ac analog sampling is simplified , and a compensation algorithms for phase error due to sequence - sampling is brought forward . for the measurement of impulse - width signals such as rotor - speed and rotor - position - angle , an intelligent interface card based on isa bus is designed . all programs for measure and control based on c + + are compiled and debugged and the flow for system debugging is summarized
    為了提高實(shí)時(shí)性,對交流采樣算法進(jìn)行了簡化,并提出了由于非同步順序采樣所造成的相位誤差的補(bǔ)償算法;針對轉(zhuǎn)速、轉(zhuǎn)子位置角等脈沖寬度信號(hào)的測量,深入分析了測量原理,設(shè)計(jì)了基于isa總線的智能接口卡;編制和調(diào)試了基于c + +的全部測量控制程序;完成了整個(gè)系統(tǒng)的調(diào)試,并總結(jié)了調(diào)試方法。
