Question

Which among the following systems are described by partial differential functions?

(a) Causal Systems and Dynamic systems

(b) Distributed parameter systems and linear systems

(c) Distributed parameter systems and Dynamic systems

(d) Causal systems and linear systems

This question was addressed to me in examination.

Asked question is from System Classification and Properties in section Signals and Systems Basics of Signals and Systems

Answer 1

Right choice is (c) Distributed parameter systems and Dynamic systems

Best explanation: In distributed parameter systems, signals are functions of space as well as time. In dynamic systems the output depends on past, present and future values of input, hence, both of these systems are described by differential functions.
