True or False/Short Answer Questions The ramp response of a 1st order system can be oscillating. Using the state space representation, the number of rows in the matrix B is equal to the number of outputs. Closed-Loop Control systems are insensitive to external disturbances. Two physically different systems must be modeled by two different transfer functions. For an LTI system, the time derivative of the unit impulse response is the unit ramp response. If a system has two real and...
