Description |
Waveforms which are smoothed according to the oscillator frequency
in order to suppress aliasing effects.

Use this function for waves which are sufficiently smooth.
If the Nyquist frequency is exceeded the wave is simply replaced
by a constant zero wave.

saw tooth,
it's a ramp down in order to have a positive coefficient for the first partial sine

This is similar to Polar coordinates,
but the range of the phase is from 0 to 1, 0 to 2*pi.

Specify the wave by its harmonics.
The function is implemented quite efficiently
by applying the Horner scheme to a polynomial with complex coefficients
(the harmonic parameters)
using a complex exponential as argument.
