Question 2:
How does the intensity of light change during the day?
Answer:
The intensity of light gradually increases in the morning, remains constant throughout the day, and gradually decreases in the evening.

Question 3:
What is an example of a continuous signal in a car's movement?
Answer:
The velocity of a car traveling from one place to another is a continuous signal, even when it accelerates or decelerates.

Question 4:
How are digital quantities different from analog quantities?
Answer:
Digital quantities are discrete and represent measurements at specific intervals, unlike continuous analog quantities.
Chapter: 1
Question 5:
What happens when a continuous signal is under-sampled?
Answer:
When under-sampled, the reconstructed digital signal differs significantly from the original, missing key peaks and dips.

Question 6:
What are Analogue Electronic Systems used for?
Answer:
Analogue Electronic Systems process continuous signals represented as continuous voltage or current signals.
Chapter: 1
Question 7:
What role do transducers play in Analogue Electronic Systems?
Answer:
Transducers convert continuous quantities into continuous voltage or current signals in Analogue Electronic Systems.
Chapter: 1
Question 8:
How do Digital Electronic Systems represent quantities?
Answer:
Digital Electronic Systems represent quantities by sampling continuous signals and processing them as discrete values.
Chapter: 1
Question 9:
Why can't Digital Systems use voltages to represent very large numbers?
Answer:
Digital Systems can't use voltages to represent very large numbers because the required voltage values would be impractically large.
Chapter: 1
Question 10:
What voltage levels do Digital Systems use to represent binary states?
Answer:
Digital Systems use +5 volts to represent a logic high (1) state and 0 volts to represent a logic low (0) state.
