tanh()-funksjonen
• Signalet multipliseres med en hyperbolsk tangent
A linear transfer function
(signal unmodified)
tanh(x*2) transfer function
tanh(x*4) transfer function
tanh()-funksjonen
Sinuskurve
Sine with tanh distortion, gain = 1
Sine with tanh distortion, gain = 3
Sine with tanh distortion, gain = 7
Waveshaping
Waveshaping – Lytte eks 1
Vi behandler en sinusbølge følgende funksjon
Example transfer function for waveshaping, rising sigmoid.
Sine waveshaped with rising sigmoid shaped
transfer function
Waveshaping – Lytte eks 2
Vi behandler en sinusbølge følgende funksjon
Example transfer function for waveshaping, rising sigmoid plus 4th harmonic sine component.
Sine waveshaped with sigmoid and 4th
harmonic sine transfer function
Waveshaping – Lytte eks 3
Vi behandler en sinusbølge følgende funksjon
Example transfer function for waveshaping, arbitrary linear
segments.
Sine waveshaped with arbitrary linear segment
transfer function
