Impulse reaction function

WitrynaWhat is impulse? Impulse is a term that quantifies the overall effect of a force acting over time. It is conventionally given the symbol \text {J} J and expressed in Newton-seconds. For a constant force, \mathbf {J} = … Witryna14 maj 2024 · We will describe the meaning of the convolution more fully below. To understand the impulse response, first we need the concept of the impulse itself, also known as the delta function δ(t). Think of a rectangular box centered at time zero, of width (time duration) ϵ, and height (magnitude) 1 / ϵ; the limit as ϵ 0 is the δ function.
