常見例句In addition, the transmission performances of NRZ and RZ code are compared. 此外,還對非歸零碼(NRZ)和歸零碼(RZ)的傳輸性能進(jìn)行了比較。In baseband transmission system,the transform between NRZ and HDB3 is usually needed. 在基帶傳輸系統(tǒng)中常需要進(jìn)行NRZ碼和HDB3碼間的相互轉(zhuǎn)換。In this work ,we employ NRZ format ,distributed Raman amplification(DRA). No FEC technology is used in the system. 系統(tǒng)采用NRZ碼,分布式拉曼放大器(DRA),無前向糾錯(cuò)(FEC)技術(shù)。NRZ encoding relies on the signal level found in the timing window to determine the binary value for that bit period. NRZ編碼依據(jù)時(shí)序窗中訊號(hào)位準(zhǔn)來決定位元周期內(nèi)的二進(jìn)位值。NRZ) is a digital-to-digital polar encoding method in which the signal level is always either positive or negative. 非零編程(NRZ)是一種數(shù)字編碼技術(shù),在它的編碼中要么正電平要么負(fù)電平。In order to obtain it, NRZ code must be processed and transferred into RZ codes. 這種傳輸方式稱為同步時(shí)鐘自恢復(fù)方式。 返回 NRZ
