Detailed Solution
Download Solution PDFThe correct answer is option '2'.
Calculation:
(4 – 2cosωt) volts
By virtual ground concept:
V+ = V-
\({V_ + } = \frac{R}{{2R}}(4 - 2\cos \omega t) + \frac{R}{{2R}}\left( { - 4} \right)\)
V+ = 2 – cos ωt – 2 = - cos ωt
\({V_{out}} = \left( {1 + \frac{{3R}}{R}} \right)\left( { - \cos \omega t} \right)\)
= - 4 cos ωt
