calculate the gain assume op amp is ideal 100k In 1k 1k Out

calculate the gain. assume op amp is ideal

Solution

here the circuit is both combination of inverting and non inverting case so to calculate the gain we have to use both the gain equation here...i uploaded the particular equations below follow these equations

FOR AN INVERTING CASE NOTHING BUT THE SECOND SECTION IN THE GIVEN FIGURE

V_out/V_in=A_v=-R₂/R₁ (Vin is nothing but v1)

_{FOR NON INVERTING CASE NOTHING THE 1ST SECTION WHICH THE INPUT IS APPLIED FOR THAT SECTION} V_out/Vin=Av=1+R₂/R₁(V_in is nothing but V2)
