Abstract :
The input and output degrees of freedom of a system are defined as the minimum number of system inputs required to excite all system modes and the minimum number of system outputs required to observe all system modes, respectively. An explicit procedure is given for determining these degrees of freedom. The usefulness of this information is considered and an example is given.
