Description
This resource introduces students to the differences between analog and digital signals. Students will learn that digital signals have some advantages over analog signals. Students will learn about using wave technology to encode information and that waves can be used for communication purposes. This resource is aligned with NGSS MS-PS4-3. Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.
It is also aligned with
Utah SEEd Standard 8.2.6
Obtain and evaluate information to communicate the claim that the structure of digital signals is a more reliable way to store or transmit information than analog signals. Emphasize the basic understanding that waves can be used for communication purposes. Examples could include using vinyl records vs. digital song files, film cameras vs. digital cameras, or alcohol thermometers vs. digital thermometers. (PS4.C)
