Analogue

Analog signals have continuous variations in amplitude or frequency, unlike digital signals which have discrete values. While analog signals can be more accurate, they degrade over long distances and carry less information per second compared to digital signals.

What is a key characteristic of an analog signal?

• It is always more accurate than digital signals.

• It carries more information per second than digital signals.

• It is continuous in nature.

• It has discrete values.

How do digital signals differ from analog signals?

• They are always less accurate.

• They have continuous variations.

• They have discrete values like on or off.

• They degrade over long distances.

Which of the following is true about analog signals over long distances?

• They are unaffected by distance.

• They maintain their quality.

• They carry more information per second.

• They can lose their quality.

What is a disadvantage of analog signals compared to digital signals?

• They are unaffected by distance.

• They carry less information per second.

• They have discrete values.

• They are always less accurate.

Which type of signal is more likely to degrade over long distances?

• Digital signals

• Neither degrades

• Analog signals

• Both degrade equally
