A physical system can be modeled by the following transfer function Y (s)/U(s) = 6s + 24 / s^2 + s − 6 if an input u(t) = δ(t) is applied to the system at t = 0 where δ(t) is a unit impulse and U(
Un sistema físico se puede modelar mediante la siguiente función de transferencia \[ \frac{Y(s)}{U(s)}=\frac{6 s+24}{s^{2}+s-6} \] si al sistema se le aplica una entrada \( u(t)=\delta(t) \) en \( t2 answers -
