We would advise you to complete this lesson on a desktop device as you need to download and interact with additional files as part of the learning. These can be downloaded from the last slide of the worksheet. You should always ask your parent or carer for permission before downloading files from the internet. Tracing the steps of a hiker through the altitude data that she transmits, learners will familiarise themselves with the basic concepts necessary for understanding any analogue to digital conversion; samples, sampling rate, and sample size.
