Control Systems Certain control system has input u(t) and output c(t). If the input is first passed through a block having transfer function e-s and unit gain is applied to the applied to the system. The modified output will be c(t-1).u(t) c(t).u(t-1) c(t-1).u(t-1) c(t)u(t) c(t-1).u(t) c(t).u(t-1) c(t-1).u(t-1) c(t)u(t) ANSWER DOWNLOAD EXAMIANS APP
