We studied the words ANALOG vs. DIGITAL.Analog, continuous wave, degradeable
Digital, sampled wave, not degradeable in terms of sound quality.
AMPLITUDE: I actually drew this incorrectly for the class - I told them the amplitude is the height of a wave from peak to trough, but it's actually half that. Just from the middle up or down. Same concept, measuring size of the wave, but it bothers me if they remember my notation of the whole wave.
