"विस्तृत पट्टी": अवतरणों में अंतर

▲'''Broadband''' in [[telecommunications]] is a term which refers to a signaling method which includes or handles a relatively wide range of [[frequency|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]], greater is 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 frequency|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 a [[modem]] will transmit a bandwidth of 64 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 can be achieved over a [[fibre optic]] circuit, for example).
