294. System Properties

1. Which of the following represents the stability of a system?

The system's response to a bounded input
The system's response to an unbounded input
The system's impulse response
The system's frequency response

2. A system is said to be causal if:

The output depends only on future values of the input
The output depends only on past and current values of the input
The output depends on all values of the input
The system is unstable

3. A system is linear if:

The output is directly proportional to the input
The output is independent of the input
The system has both memory and feedback
The system produces an identical output for different inputs

4. Which property defines if a system is time-invariant?

The system's response does not change over time
The system's response changes only with the frequency of the input
The system produces an output identical to the input
The system responds differently based on input time

5. A system is said to be stable if:

The system produces a bounded output for any bounded input
The system has an unbounded response for any input
The system has no feedback mechanism
The system's output always equals zero

6. What does it mean for a system to be memoryless?

The output at any time depends only on the input at that same time
The output depends on past inputs
The output depends on future inputs
The system has infinite memory

7. Which of the following is an example of a time-varying system?

A system whose response changes with time
A system whose response is constant over time
A system that depends only on present input
A system with a fixed frequency response

8. What does the term "invertible system" mean?

The system can reverse its output to produce the original input
The system is non-linear
The system produces an output identical to the input
The system has a constant output

9. Which of the following is a property of a stable system?

The system produces a bounded output for a bounded input
The system produces an unbounded output for a bounded input
The system's output always oscillates
The system's output never changes

10. A system is non-linear if:

The output is not directly proportional to the input
The system has feedback mechanisms
The output is always proportional to the input
The system is time-varying
