Answer 1

ANSWER:

Given that

Solution: According to given information, → alven, Vo = vg + 2VI2 - 9V IZ TUVIU According super position theorem total response vo ºs equal to sum of individual responses. VILA IR num VII am alok → from voltage division rule va = VII x P a 801/2 - we know that for an op-amp Vo = va = VII For an Investing op-amp Voi = (1+ R3 ) Vz Voi = (1+ PIR) VE vel = VII— 0 2012 2

Now, va = V2 x P e =VI2/2 from Uruit [Vo=va] - Now for Inveuting op aup - Vos = (1 + R3/R) Vi VO2 = (1 + R (213) "2 [voz = 2VI2) uviu i a R/A ma monumda 1 mum F VIUR Now, va = VIL/2 y on op aup [vb=va] - Voz = (1+ R3/R) Vj Nog = (1+ e cerz)) Voz = UVI4] -avazi Vizenemma mtup p-

for V6=0 > va = b =0) an Inveuting op-amp - Yo = - Rovi 2-R VI 3 Ria (voa-qV3 So, Vo=vo, toz toz thou Vo=V1 +2V2 -9 VE 3 +UVfL ciruit diagram : 외가 wt3 R19 VII namin VIza vIya mtu
