Frekvensomfång

Frekvensomfång, often translated as frequency response or bandwidth, refers to the range of frequencies that a particular system, device, or medium can accurately reproduce or transmit. In audio, it describes the spectrum of sound frequencies that a speaker, microphone, or audio system can produce or capture. A wider frequency response generally indicates a more accurate and detailed reproduction of sound.

In electronics and telecommunications, frequency response defines the range of frequencies over which a circuit or communication channel can operate effectively. For example, a radio receiver has a specific frequency response that determines which radio stations it can tune into. The bandwidth of a network connection, such as internet speed, is also a form of frequency response, indicating the range of data frequencies it can handle.

When discussing optical systems, frequency response relates to the range of light frequencies or wavelengths that a sensor or optical component can detect or transmit. In signal processing, it describes how a system modifies the amplitude and phase of different frequency components of an input signal. Understanding frequency response is crucial for designing and evaluating the performance of systems across various scientific and engineering disciplines.
