smalbandige

Smalbandige is an adjective used in Scandinavian languages to describe systems, signals, or devices that operate within a narrow portion of the electromagnetic spectrum. The term denotes limited bandwidth, in contrast to wideband or broadband systems.

In telecommunications and radio engineering, smalbandige solutions emphasize longer range and lower power consumption, often with simpler hardware and less spectrum usage. They are typically chosen when reliability, interference tolerance, or efficiency in a crowded spectrum are more important than very high data throughput. Narrowband signals are easier to filter and can provide better selectivity in congested environments.

In spectroscopy and imaging, smalbandige filters or detectors are tuned to specific wavelengths, enabling selective detection and improved signal-to-noise by excluding neighboring wavelengths. This makes them useful for focused measurements and imaging where only particular spectral features are of interest.

The term is widely used in Norwegian, Danish, and Swedish contexts, with variations in form and spelling. It is related to the general concept of narrowband as opposed to broadband or wideband and is commonly discussed in relation to modulation, filtering, and spectral efficiency.
