Front

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

Back

Through a process called sampling.

Front

What is an analog signal?

Back

A signal that varies continuously and can take any value within a range.

Front

What is a digital signal?

Back

A signal that represents data as discrete values, typically 0s and 1s.

What is sampling in the context of signal conversion?

Back

The process of taking measurements of an analog signal at regular intervals.

Front

What is noise in signal transmission?

Back

Unwanted alterations to a signal that can distort the original information.

Front

How do digital signals improve data integrity?

Back

They can be encoded and compressed, making them less susceptible to noise.
