摘要：
The spatiotemporal instability of a nonlinear wave is studied by applying impulse-response analysis. The time-asymptotic Green function is obtained analytically for both modulationally stable and unstable cases. The conditions for absolute and convective instability are found analytically, as is the frequency region for amplification and the spatial and temporal growth rates.
