Fourier Analysis

Additive (Fourier) Synthesis

Applying Fourier Analysis Yields a
"Frequency Spectrum"

Handy Fourier Facts:

  • Any waveform can be represented by a
    combination of sinusoids.

  • But! It might take an infinite number of sinusoids.

  • For a digitally sampled signal of length N
    It will take at most N/2 sinusoids to represent it.
