MCQ (Single Correct Answer)

-0.6

The circuit in the figure employs positive Feedback and is intended to generate sinusoidal oscillation. If at a frequency f$$_0$$, B(f)= $${{\Delta {V_f}(f)} \over {{V_0}(f)}} = {1 \over 6}\,\,\angle {0^0}$$ then to sustain oscillation at this frequency.

$${R_2}\, = \,5\,\,{R_1}$$

$${R_2}\, = \,6\,\,{R_1}$$

$${R_2}\, = {{{R_1}} \over 5}$$

$${R_2}\, = {{{R_1}} \over 6}$$
