Consider the following thransfer function of a system 2(s + 1)(s+2) s(s+3) (s+4) G = 1. Use zpk function to define the transfer function of the system and store the result in the variable "sys". 2. Use the impulse function to plot the impulse-response of the system. Script 1 sys=% Define the transfer function of the system 2 plot the impulse-response of the system Save
