- The higher the voltage the higher the sound pressure, the lower the voltage the lower the sound pressure
- Sound is air being compressed and pulled apart
- A way to represent the numbers we want to add is encoding and 2 wires for voltages are used to transfer the information
2 things you don't understand
- Cutting the range intro fractions and being unsure whether the reader will be able to understand it
- How could they cut the range into 2 pieces to encode?
1 thing you would like to know more about
- Why they send voltages in one digit at a time
