The conversion of analog signals or other information into a numeric format for transmission over radio. Used for security and/or efficiency, or to send data over radio.
A method of encoding information for transmission is expected to eventually replace analog transmission.
The process of Modulation, where the modulating wave or signal is digital and the amplitude, frequency or phase of the carrier wave or signal is varied in discrete steps according to the content of the modulating signal.
A method of encoding information for transmission that will eventually replace all analog transmission. Digital modulation reduces voice to binary code -- the zeros and ones of computer language. At the receiving end, the information is reconverted. Digital transmission offers stronger reception, less static, greater call handling capacity, fewer dropped calls, improved call privacy, and the potential for additional voice and data service such as fax and computer data transmission.
A new method of encoding information for transmission that is replacing standard analog. The information, or in this case, voice conversation, is turned into series of digital bits - the 0s and 1s of computer binary language. At the receiving end, the information is converted back into recognizable speech. Digital transmission offers a cleaner signal, virtually immune to the problems that plague analog modulation such as fading and static. (To appreciate the difference, compare the fidelity of a standard LP record, complete with background noise caused by dust hiss, with that of one of the new digital compact discs.) Digital transmission also has been embraced by the cellular industry because it offers major gains in capacity compared to analog.
A method of decoding information for transmission. Information, or in this case, a voice conversation is turned into a series of digital bits; the 0s and 1s of computer binary language. At the receiving end, the information is reconverted.
A method of encoding information for transmission. Information (in most cases a voice conversation) is turned into a series of digital bits – the 0s and 1s of computer binary language. At the receiving end, the information is reconverted to its original form. Digital transmission offers a cleaner signal and is less immune to the problems of analog modulation such as fading and static.
Digital modulation (also referred to as shift keying) is a modulation in which the modified parameter of the carrier signal can take only discrete values. This type of modulation can sometimes be referred to also as discrete modulation or manipulation, e.g.: discrete frequency modulation, amplitude manipulation (on-off keying), etc.
