Wideband

From Wikipedia, the free encyclopedia

In communications, wideband is a relative term used to describe a wide range of frequencies in a spectrum. A system is typically described as wideband if the message bandwidth significantly exceeds the channel's coherence bandwidth.

A wideband antenna is one with the approximately or exactly the same operating characteristics over a very wide passband. Distinguished from broadband antennas, where the passband is large, but the gain and or pattern need not stay the same over the passband.

Wideband in speech services means that the used speech frequency response covers 50-7000 Hz. The opposite of wideband is narrowband.
