Taajuusvasteella
Taajuusvasteella, known in English as frequency response, is a fundamental concept in signal processing and system analysis. It describes how a system, such as an audio amplifier, a filter, or a communication channel, responds to different frequencies. Essentially, it quantifies how much the system amplifies or attenuates signals at various frequencies, and how it shifts their phase.
A common way to represent the frequency response is through a graph. The horizontal axis typically displays
In audio systems, a flat frequency response is often desirable to reproduce sound faithfully. However, in other
