FWEO is further utilized to highlight the potential impulsive characteristics, and ... Witrynaimpulse (sys) plots the response of a dynamic system model to an impulse input. The model sys can be continuous or discrete. For continuous-time sys, the impulse input is the Dirac impulse δ (t). For continuous-time sys with direct feedthrough, impulse ignores the infinite pulse at t = 0.
