Static and Dynamic Systems Quiz

Give an example of a static system.

• Resistor

• Capacitor

• Inductor

• Flip-Flop

Choose the correct statement concerning a time-invariant system.

• The output response of the system does not vary with time.

• Output increases with a delay in the input

• The output decreases with a delay in the input

• Output decays to 0 with a delay in the input

Identify the causal system from the following.

• y[n] = 2x[n] + 3

• y[n] = 2x[n] - 3x[n+1]

• y[n] = 2x[n]*3x[n+1]

• y[n] = 2x[n+1]+3x[n]

Examine the property of the system y[n] = x[-n].

• non-causal

• causal

• static

• time-invariant
