    What distinguishes analogue quantities from digital quantities?

    Analogue quantities are continuous, while digital quantities are discrete.

    What is the consequence of under-sampling a continuous signal?

    It results in a reconstructed signal that significantly differs from the original.

    How do digital systems represent values?

    Using two voltage levels: +5 volts for logic high and 0 volts for logic low.

    What happens if the number of samples in digital representation is increased?

    The representation closely matches the actual continuous signal.

    What is the role of transducers in analogue electronic systems?

    They convert continuous quantities into continuous voltage or current signals.

    How do digital electronic systems process signals?

    They sample continuous signals into discrete values using Analogue to Digital Converters.

    What is a key limitation of digital systems in representing values?

    They cannot effectively represent very large or continuous ranges of values.

    What defines the binary number system?

    It allows representation of multiple values using two states: 0 and 1.

    What is the effect of reducing the number of samples to half?

    The reconstructed signal will miss critical features of the original signal.

    What is the primary function of digital systems?

    To process and represent discrete samples of continuous signals.
