This is a networking technology that uses a line's entire available bandwidth to transfer a single signal of digital data. Signals are not modulated and only one kind of signal (voice or data) can be sent at a time.
Audio, Video: signal that is not modulated onto another carrier (such as being modulated to channel 3 or 4). Computers, Networking: A data transmission format where each conductor only carries a single channel. Compare to Broadband.
Basic direct output signal in an intermediate frequency obtained directly from a television camera, satellite television receiver, or video tape recorder. Can be viewed only on studio monitors. Requires a modulator to convert the baseband signal to one of the VHF or UHF television channels in order to display on a conventional television set.
Transmission scheme in which the entire bandwidth, or data-carrying capacity, of a medium (such as a coaxial cable) is used to carry a single digital pulse, or signal, between multiple users. Because digital signals are not modulated, only one kind of data can be transmitted at a time.
A signaling technique in which the signal is transmitted in its original form and not changed by modulation. Local Area Networks as a whole, fall into two categories: baseband and broadband. Baseband networks are simpler and cheaper; the entire bandwidth of the LAN cable is used to transmit a single digital signal. In broadband networks, the capacity of the cable is divided into channels, which can transmit many simultaneous signals. Broadband networks may transmit a mixture of digital and analog signals, as will be the case in hybrid fiber/coax interactive cable television networks.
The signal or signals that are used to modulate the radio carrier in the transmitter, and in this way the information can be carried by the radio signal. They may often be referred to as modulation. The baseband signals are recovered by the receiver by demodulating the received radio signal.
A transmission scheme that does not employ carrier modulation. In digital baseband systems, data is sent by varying the voltage (pulse amplitude modulation â€“ PAM) or the duration (pulse width modulationâ€”PWM) of signal pulses to indicate different values. Baseline Privacy Interface (BPI) A set of extended services within the DOCSIS MAC sublayer. BPI gives subscribers data privacy across the RF network, encrypting traffic flows between the cable modem termination system (CMTS) and cable modem (CM).
The range of frequencies occupied by the source electrical signal that is to be transmitted over a radiocommunications link. It is the frequency band occupied by an analogue or data signal prior to modulation and frequency conversion, or after frequency conversion and demodulation. For example, the baseband of a video signal extends from 0 Hz to about 5 MHz.
is a network or other telecommunication system in which information is carried in digital form on a single unmultiplexed signal channel on the transmission medium. This usage pertains to a baseband network such as Ethernet and Token Ring local area networks (LAN). See also Broadband.
A technique whereby digital input is directly applied to transmission media without the intervention of a modulating device. Baseband is generally applied in an environment with high bandwidth over a short distance. It is generally considered easier and more cost-effective than broadband. Ethernet, token ring, FDDI, and ATM generally use baseband.
The actual audio (0-20 kHz) and video information (0-4.2 MHz) that is modulated onto a carrier for transmission over the air or on a cable system. It is also the audio and video information that is detected (demodulated) by the set-top box or TV set for the customer's viewing and listening pleasure.
the frequency band occupied by all the transmitted signals that modulate a particular carrier. The band that transmits picture and synchronising signals in television is one example; another is the band containing all the modulated subcarriers in a carrier system.
Local area networks generally fall into two categories: baseband and broadband. In baseband, the entire bandwidth (capacity) of the LAN cable is used to transmit a single digital signal. See broadband.
Baseband is the name given to a transmission method in which the entire bandwidth (the rate at which information travels through a network connection) is used to transmit just one signal. Baseband is a cheaper method than broadband and is typically used for shorter distances of transmission. The digital signals that are carried via baseboard are un-modulated meaning that the signal is not adjusted before hand. Baseboard is commonly used in LAN networks (Local Area Networks) that are most commonly used in offices.
A prime signal such as composite video, component video and audio having its own path and that is not modulated onto a carrier signal or combined with other signals on a path. An unmodulated signal or band of signal. The video signal seen on a waveform monitor is baseband video signal.
The frequency band occupied by the aggregate of the signals used to modulate a carrier before they combine with the carrier in the modulation process. In CCTV the majority of signals are in the baseband.
A form of modulation in which data signals are pulsed directly on the transmission medium without frequency division and usually utilize a transceiver. In baseband the entire bandwidth of the transmission medium (e.g., coaxial cable) is utilized for a single channel.
The basic direct output signal in an intermediate frequency based obtained directly from a television camera, videoconference television receiver, or video tape recorder. Baseband signals can be viewed only on studio monitors. To display the baseband signal on a conventional television set a "modulator" is required to convert the baseband signal to one of the VHF or UHF television channels which the television set can be tuned to receive.
The transmission technique or signal in which data from different users are combined in a serial stream for transmission along the physical media. In a baseband network, the signals are sent from one computer to another as digital pulses. Since the signals are not modulated to analog, only one kind of data can be transmitted. All baseband networks use the median (or wire) as a single communications channel, so that users must wait for channel availability in order to transmit.
The simplest method of transmission on a local area network. The entire bandwidth of the cable is used to transmit a single unmodulated digital signal. Baseband transmission is capable of accommodating multiple signals through time division multiplexing. The alternative to baseband transmission is broadband. Learn more about Baseband...
Communications signals whose bandwidth is approximately equal to the highest frequency transmitted. Compare with modulated signals (RF) where the frequencies transmitted (at the modulated carrier frequency) are much higher than the bandwidth.
A term defining any network in which the information is modulated onto a single frequency. The digital input is applied directly to the transmission media without the intervention of a modulating device, which works well if there is wide bandwidth and distances no more than several hundred meters are involved. It is common in LANs and limited distance modems. All stations attached to the network have to participate in every transmission. Baseband is simpler and cheaper than broadband, and it permits only one "conversation" at a time as the whole of the bandwidth is used to transmit a single digital signal. Ethernet is a baseband network.
A transmission medium through which digital signals are sent without complicated frequency shifting. In general, only one communication channel is available at any given time. Ethernet is an example of a baseband network.
bridge A device connecting local networks at the OSI data link layer that filters and forwards frames according to MAC addresses using transmission of a digital or analog signals at its original frequency as an un-modulated signal.
A signal without a carrier. A television camera produces baseband signals. Television monitors which accept baseband signals do not require an R.F. tuner or an I. F. detector section. Baseband audio is pure audio as from a tape recorder. Baseband video contains no audio information. For basebands to be used by a normal television, it must be modulated at the frequency of the particular channel into which it is to be fed.
The basic direct output signal from a television camera, satellite television receiver, or video tape recorder in an intermediate frequency (IF) range. Baseband signals can be viewed only on studio monitors. To display the baseband signals on a standard television the signal must be modulated to a VHF or UHF frequency which the television set has a capability of receiving.
A communications method where digital signals are pulsed directly on the transmission medium without change in modulation. In baseband LANs, the entire bandwidth of the cable is used to transmit a single signal and only one signal can be transmitted at a time. See also broadband.
Baseband is an adjective that describes signals and systems whose range of frequencies is measured from 0 to a maximum bandwidth or highest signal frequency; it is sometimes used as a noun for a band of frequencies starting at 0. It can often be considered as synonym to lowpass, and antonym to passband.
Baseband is a general term for part of the physical components of a wireless communication product. Typically, this would include the control circuitry (microprocessor), the power supply, amplifiers, etc.
