Analog Vs. Digital Signals

Front

What is the main difference between analog and digital signals?

Back

Analog signals can vary continuously, while digital signals can only have specific values.

Front

What are binary digital signals?

Back

Binary digital signals are signals that can only have two amplitude values—large and small.

Front

How do different programs use the same binary code?

Back

Each program interprets the binary code differently, allowing 1s and 0s to represent text, sound, or images.

Front

What is digital encoding?

Back

Digital encoding sends or stores information using quantities that can only have specific values.

Front

What is an advantage of digital signals over analog signals?

Back

Digital controls move objects in predictable, exact increments.

Front

How does analog encoding work?

Back

Analog encoding sends or stores information using quantities that can vary continuously.

Front

What is an example of a digital signal?

Back

A computer's binary code, which uses 1s and 0s.

Front

What is an example of an analog signal?

Back

A continuous sound wave, such as a vinyl record.

Front

Why is digital encoding preferred in modern technology?

Back

Digital encoding allows for more accurate and reliable transmission of information.

Front

What does it mean for a signal to have 'specific values'?

Back

It means the signal can only take on certain discrete values, not a range.
