passbandtransmissie
Passbandtransmissie is a term used mainly in optics and telecommunications to describe the amount of signal power that is successfully transmitted through a system within a specified frequency range, called the passband. It is often expressed as a percentage of the input power or in decibels (dB). The concept applies to optical fibres, fibre‐optic amplifiers, radio‑frequency links, and any device that exhibits a frequency‑dependent response.
In fibre‑optic links, passbandtransmissie is determined by a combination of factors. Chromatic dispersion spreads different wavelengths
For electronic RF filters, passbandtransmissie indicates how much of the desired signal frequency passes while stop‑band
