he basic idea of the method of bisection is to start with an initial interval, [a0,b0], that is chosen so that f(a0)f(b0) < 0. (This guarantees that there is at least one root of the function f(x) within the initial interval.) We then iteratively bisect the interval, generating a sequence of intervals [ak,bk] that is guaranteed to converge to a solution to f(x) = 0.

算術(shù)編碼方法是將被編碼的一則消息或符號(hào)串（序列）表示成0和1之間的一個(gè)間隔（interval），即對(duì)一串符號(hào)直接編碼成[0,1]區(qū)間上的一個(gè)浮點(diǎn)小數(shù)。符號(hào)序列越長(zhǎng)，編碼表示它的間隔越小，表示這一間隔所需的位數(shù)就越多。信源中的符號(hào)序列仍然要根據(jù)某種模式生成概率的大小來(lái)減少間隔。可能出現(xiàn)的符號(hào)概率要比不太可能出現(xiàn)的符號(hào)減少范圍小，因此，只正加較少的比特位。

Abstract: This application note describes how sampling clock jitter (time interval error or "TIE jitter") affectsthe performance of delta-sigma digital-to-analog converters (DACs). New insights explain the importanceof separately specifying low-frequency (< 2x passband frequency) and high-frequency or wideband (> 2xpassband frequency) jitter tolerance in these devices. The article also provides an application example ofa simple highly jittered cycle-skipped sampling clock and describes a method for generating a properbroadband jittered clock. The document then goes on to compare Maxim's audio DAC jitter tolerance tocompetitor audio DACs. Maxim's exceptionally high jitter tolerance allows very simple and low-cost sampleclock implementations.

針對(duì)UHF讀寫(xiě)器設(shè)計(jì)中，在符合EPC Gen2標(biāo)準(zhǔn)的情況下，對(duì)標(biāo)簽返回的高速數(shù)據(jù)進(jìn)行正確解碼以達(dá)到正確讀取標(biāo)簽的要求，提出了一種新的在ARM平臺(tái)下采用邊沿捕獲統(tǒng)計(jì)定時(shí)器數(shù)判斷數(shù)據(jù)的方法，并對(duì)FM0編碼進(jìn)行解碼。與傳統(tǒng)的使用定時(shí)器定時(shí)采樣高低電平的FM0解碼方法相比，該解碼方法可以減少定時(shí)器定時(shí)誤差累積的影響；可以將捕獲定時(shí)器數(shù)中斷與數(shù)據(jù)判斷解碼相對(duì)分隔開(kāi)，使得中斷對(duì)解碼影響很小，實(shí)現(xiàn)捕獲與解碼的同步。通過(guò)實(shí)驗(yàn)表明，這種方法提高了解碼的效率，在160 Kb/s的接收速度下，讀取一張標(biāo)簽的時(shí)間約為30次/s。 Abstract: Aiming at the requirement of receiving correctly decoded data from the tag under high-speed communication which complied with EPC Gen2 standard in the design of UHF interrogator， the article introduced a new technology for FM0 decoding which counted the timer counter to judge data by using the edge interval of signal capture based on the ARM7 platform. Compared with the traditional FM0 decoding method which used the timer timed to sample the high and low level， the method could reduce the accumulation of timing error and could relatively separate capture timer interrupt and the data judgment for decoding， so that the disruption effect on the decoding was small and realizd synchronization of capture and decoding. Testing result shows that the method improves the efficiency of decoding， at 160 Kb/s receiving speed， the time of the interrogator to read a tag is about 30 times/s.
