The impulse response function and ship motion

WebMay 17, 2024 · The impulse response function method (IRFM) is one of the methods to analyze wave-induced ship’s motions in irregular waves in the time domain. The Fourier transform relates the frequency-domain and the time-domain closely. WebIn signal processing and control theory, the impulse response, or impulse response function (IRF), of a dynamic system is its output when presented with a brief input signal, called an …
