Have you ever wondered how sound can travel from phone to phone? Well you’re in luck!

 

 As you can see to the left, that is a visual representation of how sound travels. The blue line represents what the ADC (Anologue digital converter) produces. As you can see, the two lines are pretty different. We can fix this by increasing the sampling frequency!

 

 

 

As we can see shown by the green line, increasing the sampling frequency makes the lines significantly similar. This increases the accuracy for the ADC, making your calls more clear!
