Digital vs. Analog Signals 2 Flashcard

Front

What is the main difference between analog and digital signals?

Back

Analog signals are continuous, while digital signals are discrete.

Front

What does binary code consist of?

Back

A series of 1s and 0s.

Front

How can an analog signal be converted into a digital signal?

Back

Through a process called sampling.

Front

Which of the following is an example of a digital signal?

Back

A binary code of 1s and 0s.

Front

What is a key advantage of digital signals over analog signals?

Back

They can be easily corrected to remove noise.

Front

Define analog signal.

Back

An analog signal is a continuous signal that represents physical measurements.

Front

Define digital signal.

Back

A digital signal is a discrete signal that represents data as a sequence of separate values.

Front

What is sampling in the context of signal conversion?

Back

Sampling is the process of converting an analog signal into a digital signal by measuring its amplitude at regular intervals.

Front

Give an example of an analog signal.

Back

A sound wave from a record player.

Front

What is noise in signal transmission?

Back

Noise refers to any unwanted interference that distorts the signal.
