a pure tone
What is a Complex Wave?
a wave that is composed of 2+ sine waves
Describe Superposition.
the sum of amplitudes at each moment in time; complex waves are combines by superposition
What are Components?
the sine waves that make up complex waves

harmonic; lowest
What is a Complex Aperiodic Wave?
non-repetitive
no fundamental frequency
no harmonics

Describe Fourier Analysis.
any complex waveform that can be broken down into individual sine waves
