  1. Data Representation

Amplitude is the height of the wave.

Activity

Use the Mic test to see sound wave.

  1. Loud sound generate high amplitude

  2. Soft sound generate low amplitude

Frequency is the number of cycle of wave.

Activity: Create an image and save it as BMP and JPG. Compare the file size of the 2 files.

2. Data Transmission

3. Hardware
