Exercise 1.2
Determine if the following systems are: 1. Memoryless, 2. Time-invariant, 3. Linear, 4. Causal, 5. BIBO Stable. Justify your answers.
(a)
Answer:
1. Memoryless No. For example, the output depends on a future value of the input.
2. Time-invariant No.
3. Linear Yes. Let . Then, the output of the system with is given by:
4. Causal No. For example, the output depends on a future value of the input.
5. Stable Yes. .
(b)
Answer:
1. Memoryless No. The system has memory since at time , it uses the past value of the input .
2. Time-invariant Yes.
3. Linear No. The system is nonlinear since it does not have the superposition property:
4. Causal Yes. The system is causal as the output is a f…(skip)
