<Setup>
Sine definition
  -  Number of sines  (max. 10)
  -  Index of the selected sine
  -  Number of periods over the time window
  -  Amplitude of the selected sine
  -  Phase of the selected sine  ( Ex:  0° = sine,  90° = cosine)

Modulation
  -  Period:		number of modulation periods over the time window
  -  Percent %:	modulation  percentage      max: 100%

Offset
  -  DC offset value

Damping
  -  damping coefficient

To change parameters, click onto the parameter, an input screen will be displayed.

Transform
0	uses the Transform / Inverse routines from the FFT library in this case there are 256 time samples and 256 frequency samples each frequency sample is a complex conjugate pair of values.
2	uses the Transform2 / Inverse2 routines from the FFT library in this case there are 256 time samples but only 128 frequency samples.
