This activity comprises of an interactive spreadsheet model that allows you to change the value in the yellow coloured cell to represent a percentage of noise added to a signal. It allows you to see what happens to both analogue and digital signals with the same amount of noise side by side. There is a worksheet to summarise the difference between the two kinds of signal and also an activity for pupils where they plot out signal plus noise by hand - ideal for a flipped learning approach where pupils do this in advance of the lesson before discussion in the lesson.
