Question:
"Although an incandescent light bulb appears to shine with constant intensity, this is an artifact of the eye's persistence of vision.
In fact, the intensity of a bulb's light rises and falls with time due to the alternating current used in household circuits.
If you could perceive these oscillations, would you see the light attain maximum brightness 60 or 120 times per second?" Explain.
For a system, we learn the following three properties: (1) Memoryless, (2) Time-variant, (3) Linear, and (4) Casual. Determine which of these properties hold and which do not hold for each of the following continuous-time systems.
