Encoding - Digital data to digital signals: A digital signal is a sequence of discrete, discontinuous voltage pulses, as illustrated in Stallings DCC8e Figure Each pulse is a signal element. Binary data are transmitted by encoding each data bit into signal elements. In the simplest case, there is a one-to-one correspondence between bits and signal elements. More complex encoding schemes are used to improve performance, by altering the spectrum of the signal and providing synchronization capability. In general, the equipment for e. ncoding digital data into a digital signal is less complex and less expensive than digital-to-analog modulation equipment. Data digital merupakan deretan nilai yang berbeda dan memeiliki ciri tersendiri.Contoh data digital adalah teks, bilangan bulat dan karakter lain. Masalahnya adalah karakter yang dipahami manusia tersebut tidak dapat langsung ditransmisikan dengan mudah dalam sistem komunikasi. Data tersebut terlebih dahulu harus diubah ke dalam bentuk biner. Jadi suatu data digital akan ditransmisikan dalam dereten bit.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
