4/2 Waygroud Quiz - Wave Properties and behavior

Oliver is learning about signals in his electronics class. He learned that a digital signal is best described as a signal that (a)   .

• A signal that varies continuously

• A signal that represents data using discrete values

• A signal that is always analog

• A signal that cannot be transmitted
