6. (5 points) For the Wien bridge oscillator (shown in the top right) derive the formula: wo= 1 RC for the frequency of oscillation. Also, show that the output voltage Vout is three times that of the inputs (non-inverting and inverting inputs). You should use complex arithmetic for the calculation. This circuit does not operate in saturation, so the "golden rules" are obeyed. A #327 lamp R_1 R_2 www output OP-37 f=1 2TRC R www
