Broadband Signal distribution (L-band/IF-signals)

Broadband refers to a signaling method that includes or handles a relatively wide range (or band) of
frequencies, which may be divided into channels or frequency bins. Broadband is always a relative term,
understood according to its context. The wider the bandwidth, the greater the information-carrying capacity.
In radio, for example, a very narrow-band signal will carry Morse code; a broader band will carry speech; a still
broader band is required to carry music without losing the high audio frequencies required for realistic sound
reproduction. A television antenna described as “normal” may be capable of receiving a certain range of
channels; one described as “broadband” will receive more channels. In data communications an analog
modem will transmit a bandwidth of 56 kilobits per seconds (Kbit/s) over a telephone line; over the same
telephone line a bandwidth of several megabits per second can be handled by ADSL, which is described as
broadband (relative to a modem over a telephone line, although much less than what can be achieved over a
fiber optic circuit).
