Digital vs. Analog Signals 2 Flashcard

Front

What is a digital signal?

Back

A digital signal is a type of signal that represents data as discrete values, typically using binary code (1s and 0s).

Front

What is an analog signal?

Back

An analog signal is a continuous signal that represents physical measurements, such as sound waves or light intensity.

Front

Give an example of a digital signal.

Back

A binary code of 1s and 0s.

Front

What is binary code?

Back

Binary code is a system of representing information using two symbols, typically 0 and 1, which computers use to process data.

Front

How do computers use binary code?

Back

Computers use binary code to control processes by turning circuits on and off.

Front

What is the process of converting an analog signal to a digital signal called?

Back

The process is called sampling.

Front

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

Back

Digital signals can be easily corrected to remove noise.

Front

What does it mean to convert something to a code?

Back

To convert something to a code means to assign symbols to represent information.

Front

What is noise in the context of signals?

Back

Noise refers to unwanted variations in a signal that can distort the original information.

Front

How can digital signals improve communication?

Back

Digital signals can improve communication by providing clearer and more reliable transmission of information.
