impulsekäyrä
Impulsekäyrä, often translated as impulse curve or impulse response, is a fundamental concept in signal processing and control theory. It describes the output of a system when subjected to a brief input signal, known as an impulse. An impulse is theoretically an infinitely short pulse with an amplitude of infinity, but in practice, it is approximated by a very short, high-amplitude pulse.
The impulse response is unique to each linear time-invariant (LTI) system. It essentially characterizes the system's
In practical applications, impulse responses are used in areas such as audio engineering to characterize the
