For an assignment I have to create a sinusoidal oscillator with 5 Vpp (centered around 0 V) oscillating at 10.0 kHz. The oscillator works as expected, at the right frequency, but the voltage needs to be regulated between 0 to 5 Vpp.
The following picture shows my design so far; As you can see the circuits consists of the Wien-bridge oscillator with a low-pass filter to attenuate the higher harmonics. I have tried using a voltage divider but that method does not hold for 0 to 5 Vpp. I am only allowed to use basic components, like the 741 opamp and 1N149 diodes, besides capacitors and resistors.
Does anyone know a method on how to achieve 0 to 5 Vpp regulation using these simple components?
