Microcontroller addict [Debraj] decided to make his own programmable sine wave generator ... a complete Direct Digital Synthesis (DDS) waveform generator system on a chip. If you’ve ever ...

I became aware of harmonics and the sound of different shaped waveforms early in my electronics ... I have created several sine wave sources and summed them together. Seen here, the waves combine ...

The representation of a PERIODIC sound or WAVEFORM as a sum of Fourier components (i.e. pure SINUSOIDAL WAVEs). According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs ...
