A signal which has frequencies from 0 to some band-limited value B.
OR
we can sy that baseband signal is a signal that can include frequencies that are very near zero, by comparison with its highest frequency
(e.g: a sound waveform can be considered as a baseband signal, whereas a radio signal or any other modulated signal is not baseband.)
A Baseband signalling is the way information is sent across a network. It describes the signal that is used, in this case it uses a block signal to send data across a network.
Baseband Signalling: 1)Uses digital signalling 2)No frequency-division multiplexing 3) Bi-directional transmission 4)Signal travels over short distances Broadband Signalling: 1)Uses analog signalling 2)Unidirectional transmission 3)Frequency-division multiplexing is possible 4)Signal can travel over long distances before being attenuated
give to examples for baseband
it is baseband transmission
disadvantage of in-band signalling
Baseband broadband can be define as access in which networ work
The "100" in the media type designation refers to the transmission speed of 100 Mbps. The "BASE" refers to baseband signalling, which means that only Ethernet signals are carried on the medium. The "T4," "TX," and "FX" refer to the physical medium that carries the signal.
Cellular Signalling was created in 1989.
broadband
Yes, Ethernet is very common on LANs and is a baseband transmission type.

Baseband
Electrical signals are found in different parts of the frequency spectrum. A baseband signal is an "original" signal that directly conveys the frequency range of the original: a hi-fi audio signal is commonly 20 Hz to 20 kHz, analog video (European) is 50 Hz to 5 MHz. A baseband signal *does not* use a modulated carrier, no matter how high or low its frequency. Any signal that *does* use modulation is *not* a baseband signal. Radio (and other) transmission systems use the baseband signal to modulate a carrier before sending. On reception, the modulation is extracted to become a copy of the original baseband signal.
