I´m searching for a solution to built a FM Wobbeltonegenerator to use in a Audiometer. Sigma Studio with a ADAU1701 Sigma DSP.
What the Generator Output should do: (FM Modulation)
A Generator with:
Sine Tone, with adjustable Center Frequency from 125Hz-20khz and
- adjustable depth from +/-5% up to +/-20% (depending from the Chosen Center Frequency
- adjustable Rate from 1-25Hz
The changes in Frequency (from the lowest to the highest and reverse) should be linear, or sinodial
Is there anyone in this Forum that can help me to built such a Oszillator in Sigma Studio?
