What is one difference between an analog signal and a digital signal based on the diagrams provided?

• Analog signals are continuous, while digital signals are discrete.

• Analog signals use binary numbers, while digital signals use a continuous range of values.

• Digital signals are always smooth, while analog signals have steps.

• There is no visible difference between analog and digital signals.

What is the main difference between an analog signal and a digital signal?

• An analog signal is digital, and a digital signal is analog.

• An analog signal is continuous, and a digital signal jumps from one value to another.

• An analog signal is always a straight line, and a digital signal is always a curve.

• An analog signal can only represent a limited number of values, while a digital signal can represent an infinite number of values.
