Wien bridge oscillator with limiter

[ahmed fathi]

Hello
I got that question in an exam

what would be the difference in answer , relative to the Wien Bridge oscillator wiithout limiter circuit ?!

There we got that W0 = 1/RC & R2/R1 = 2

Does the limiter affect these values ?!

All what I did different is getting the value of positive and negative peaks Assuming Ideal diods

as in here ( from sedra the Resistance names are different than the exam)
