NGSS.MS-PS4-2

Definition: Most data is sent this way and needs greater bandwidth, complex to process, travels faster and longer distance and transfers more data as compared to analog. A signal that takes two values, on and off. Typically represented by "0" or "1". They require less power by often more bandwidth than analog, and copies of these are exactly like the original. What is this type of signal?

• A) Frequency

• B) Analog Signal

• C) Transverse Wave

• D) Digital Signal
