Other than low-cost, his list of requirements was as follows: Dual sine wave output, synchronized Frequency, Amplitude, and Phase control Low harmonics under 1 MHz Scriptable via Python The heart ...

[153Armstrong] did a short post on how easy it is to generate waveforms using Python. We agree it is simple, but actually, it isn’t so much Python per se, it is some pretty cool libraries ...

According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs in the HARMONIC SERIES, where the Fourier coefficients give the AMPLITUDE and PHASE angle of each component.

Successive approximations of a SAWTOOTH WAVE by addition of harmonics with amplitude inversely proportional to the harmonic number. The resultant waveform at each stage of addition is shown at right.
