Baseband and Broadband

i googled this out so please can somebody explain these points in detail.

In a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously.



Also

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

One of your other queries

Baseband (supervisory) signalling is where signals, that give information ranging from the condition of a transmission line via issuing of permissions to use the channel to the frequencies occupued by other signals, are transmitted as a signal with its maximum frequency below those of the other signals; nominally, this should be effectively baseband - though the term is still used when the supervisory signal is Manchester encoded, for example.

Try this!

can someone actually help

Many people find Wikipedia (other on-line encyclopaediae are available) a great source of information.

did u suggest the same thing to your father, your mother and also every family member of your family too????? yes/no ????

better be a yes

ps

I am being civil.

Let's start with baseband. No, it doesn't mean that the entire available bandwidth is used. Strictly speaking, it means that the intended spectral content includes very low frequencies (mathematically that you cannot specify a non-zero frequency that is not included). Being practical people, we often use the term somewhat loosely to mean a single signal whose spectral content covers very much more than an octave. What this means in practice is that (code-division multiplex excepted) a transmission medium can normally convey only a single baseband signal - but it can also carry multiple other signals.

So far as I know, broadband is used with many different meanings. When applied to a transmission medium or an amplifier, it usually means that the bandwidth of the medium or amplifier is more than an ovtave. But it is also used to indicate a medium that carries several different channels at once, with these generally extending across more than an octave. Sometimes (naughtily in my opinion, as this is subjective) it simply means that a channel carries a lot of information (a bit like New College, now 620 years old?)
