frekvensåtergivning
Frekvensåtergivning, often translated as frequency response, describes how accurately a system reproduces different frequencies within its operating range. In audio systems, this refers to how a loudspeaker, amplifier, or recording device reproduces sound at various pitches. A perfectly flat frequency response would mean all frequencies are reproduced at the same volume level. However, real-world systems have deviations.
The frequency response is typically measured and represented graphically, with frequency on the horizontal axis (usually
In fields beyond audio, frequency response can also describe the behavior of other systems. For example, in
