Things I learned:
-Analog Signal: A signal that is proportional to the value it represents
-Digital Signal: A signal that represents a value as a series of discreet values or digits
-Base Numerals: Representing a number using "n" digits
Things I didn't understand:
-The analog systems was confusing, I didn't fully understand how it works.
-I did not understand how the sound waves worked when this topic was applied to the speaker of cell phones. Also, the way sound traveled through the metal wire in headphones confused me a lot.
Something I want to learn:
-I want to learn sound wave frequencies and how to separate them from each other. I would also like to know more about how sound wave comes into play in this.
