A mode of transmission in which all information is transmitted in digital form as a serial stream of pulses. Sound waves and other information are converted into binary computer code (a series of 0s and 1s) and transmitted to the end point. At the end point, binary code is converted back into the original format. Digital transmission provides sharper, clearer, faster transmission than analog transmission.
In digital transmission, the continuously varying signals of pictures and sound are converted into discrete values represented in binary form by 0s and 1s. These bits of information are then sent as a series of on-off pulses by varying the phase, frequency or amplitude of carrier waves.
a compressed electronic signal where information is transmitted in the form of numbers so signals can be mathematically manipulated to eliminate redundant or unwanted information to occupy less bandwidth. ETV's 32-channel satellite capability is possible because of digital transmission.
A system for sending information over access lines where sound waves and other information are transmitted in a series of on and off pulses, or beeps. This type of transmission is sharper, clearer and quieter than analogue transmission. (See analogue)
The use of a binary code to represent transmitted information. A digital transmission is much cleaner then an analogue transmission. In analogue transmission, the signal, along with all the garbage it picks up, is simply amplified. In digital transmission, the signal is first regenerated.
A way of encoding information as a series of 'on' or 'off' signals. Extremely rapid sequences of such information can be transmitted and decoded to reproduce human speech, computer-generated data or video signals.
Sound waves and other information are converted to binary computer code (a series of 0s and 1s). The information is sent in this format, then converted into its original format when it reaches its destination.
Method of storing, processing and transmitting information through the use of distinct electronic or optical pulses that represent the binary digits 0 and 1. Digital transmission and switching technologies employ a sequence of these pulses to represent information as opposed to a continuously variable analog signal. The precise digital numbers preclude any distortion such as graininess or snow in the case of video transmission, or static or other background distortion in the case of audio transmission.
In analog transmission, the signal, along with all the other garbage it picked, is simply amplified. In digital transmission, the signal is first regenerated . the signal is reconstructed to what it was, identically. Then it is amplified and sent on its way. So digital transmission is much cleaner than analog transmission. The second major benefit of digital transmission is that the electronic circuitry to handle digital is getting cheaper and more powerful while analog transmission equipment, less and less, lends itself to the technical breakthroughs of recent years in digital.
A mode of transmission in which all information to be transmitted is first converted to digital form and then transmitted as a serial stream of pulses. Any signal-voice, data, television-can be converted to digital form.
Converts sound waves and other information into binary computer code, which is a series of zeroes and ones. The information is sent in digital format and is then converted back to its original format when it reaches its destination. This provides sharper, clearer and faster transmission than analog transmission, because it can be repeated without introducing noise.
