Digital vs. Analog Signals

Front

What is an analog signal?

Back

An analog signal is a continuous signal that represents physical measurements. It can take any value within a given range.

Front

What is a digital signal?

Back

A digital signal is a discrete signal that represents data as a sequence of separate values, typically in binary form (0s and 1s).

Front

How do analog signals differ from digital signals in terms of reliability?

Back

Digital signals are more reliable than analog signals because they are less susceptible to noise and interference.

Front

Can analog signals be easily corrected to remove noise?

Back

No, analog signals are not easily corrected for noise, while digital signals can be.

Front

What type of signal is music played from a record?

Back

Analog signal.

Front

What type of signal is a video game coded as?

Digital data.

Front

What is an example of a device that uses analog signals?

Back

A traditional radio uses analog signals to transmit sound.

Front

What is an example of a device that uses digital signals?

Back

A computer uses digital signals to process and store data.

Front

What are the advantages of digital signals over analog signals?

Back

Digital signals are more reliable, can be compressed, and are easier to store and transmit.

Front

What is noise in the context of signals?

Back

Noise refers to any unwanted interference that distorts the original signal.
