Impact of sampling time on sampling effect of 采樣器采樣效果的影響
On the other hand , the interharmonics are always various , so it is not fit to adopt short sampling time 而且間諧波源時時發(fā)生變化,采樣時間也不能過長。
It was chased down that general dimension series value changed with the variation of the sampling time and noise 計算了標(biāo)準(zhǔn)信號的廣義分形維數(shù),找出了廣義維數(shù)序列值隨信號的采樣時間、噪聲變化而變化的特點。
In this paper , signals of heart beat rate are collected from 15 healthy youth , all of them are between 20 to 30 years old , the sampling time is about 30 minutes 本文采集了15例年齡在20 - 30歲之間的健康青年人的心率信號,采集時間為30分鐘左右。
The results are that the less the sampling time interval , the nearer the estimated price volatility to that in ultra - high - frequency data 價格服從維納過程時,用甚高頻資?和高頻資?分別估計?價格波動? ;估計結(jié)果表明:采樣時間片越大,與甚高頻估計結(jié)果差距越大。
Author suggests that increasing number of measurement taps and prolonging sampling time and enhancing sampling frequency will decrease signals aliasing and leakiness 并提出在進(jìn)行壓力脈動試驗時,應(yīng)增加測點、延長采樣時間、提高采樣頻率以避免信號遺漏和信號混疊等現(xiàn)象的發(fā)生。
In this chapter , how to accumulate sampling time in network control system is analyzed at first , because every network control system will face this problem 選取合適的控制器采樣周期是網(wǎng)絡(luò)實時控制系統(tǒng)設(shè)計必須面臨的問題,文中根據(jù)網(wǎng)絡(luò)管理系統(tǒng)特有的性質(zhì),提供了采樣周期選擇原則。
A system that regulates sampling time according to countrate level therefore can reduce this error significantly and its performance is verified by monte ? carlo simulati on 實踐證明,這種爆破技術(shù)減少了對圍巖的破壞,提高了巷道的成形質(zhì)量,降低了材料消耗,有利于提高掘進(jìn)速度和降低工程成本。
There are three main problems in different building blocks that will impair the dynamic performance of ultrahigh speed adc . they are offset , sampling time uncertainty and signal - dependent delay 從失調(diào)電壓、采樣時間不確定性和相關(guān)輸入信號延遲三個方面,分析了系統(tǒng)動態(tài)性能對系統(tǒng)組成電路模塊的要求。
In this paper , it is introduced to the influence of cavitation factor , measurement taps , sampling frequency and sampling time on the test result in pressure fluctuation test of the water turbine 摘要介紹了水輪機壓力脈動試驗時空化系數(shù)、測量位置及測點、信號采樣頻率及采樣時間等因素對試驗結(jié)果的影響。
