Analogue & digital

The differences between analogue and digital communication

From founding communications, such as the fire beacon, to being able to communicate with space, there is no denying that developments in communication have advanced at a rapid speed. This topic presents students with communications of the past, present and future, helping them to understand the principles that form the basis for these developments.

Activity info, teachers' notes and curriculum links

An engaging activity introducing students to the differences between analogue and digital communication. An analogue signal can be rendered useless by small amounts of interference, whereas a digital signal remains coherent.

The activity sheet includes teacher notes, guidance, useful web links, and links (where appropriate) to the national curriculum in each of the four devolved UK nations; England, Northern Ireland, Scotland and Wales.

Remember, it's all free!...and registration is free too!

All activity sheets and supporting resources (including film clips!) are free to download, and all the documents are fully editable, so you can tailor them to your students' and your schools' needs.
