3. Spectrum Representation Demos
 |
3-3,4,5,6 Beat Note | p41,42 - Shows the effect of multiplying two sinusoids that are close in frequency. |
 |
FM Synthesis |
p63 - This demo gives the mathematical derivation of how instrument sounds can be
synthesized using the principles of frequency modulation.
The example sounds include a bell and a clarinet.

3-14,17,19,20 Fourier Series Demo | p52,54,56,57 - Shows how any periodic signal can be approximated as a sum of sinusoids. It allows you to choose from several input signals and creates an approximati on to the signal you choose. You can select how mnay cosine terms to use in the approximation. |
