The limitation of the transfer function approach are:
A. The spectral factorization becomes quite complex
B. It is restricted to the systems with all performance index
C. Multi input and multi output systems are not obvious
D. It is useful for time varying and linear systems
Answer:A
The limitation of the transfer function approach are:
A. The spectral factorization becomes quite complex B. It is restricted to the systems with all performance index C. Multi input and multi output systems are not obvious D. It is useful for time varying and linear systems
Explanation: The limitation of transfer function approach is that is it useful only for quadratic performance index and multi input and multi output systems are obvious and also it is ineffective for time varying and non-linear systems.
