Taajuusvasteen
Taajuusvasteen, which translates to frequency response in English, is a fundamental concept in signal processing and systems analysis. It describes how a system, such as an audio amplifier, a filter, or a communication channel, responds to different frequencies within its operating range. Essentially, it quantifies how the system amplifies or attenuates signals at various frequencies, and how it might introduce phase shifts.
The frequency response is typically represented graphically as a plot with frequency on the horizontal axis
In addition to magnitude, the phase response is also an important aspect of the frequency response. It
