Hello! I am trying to answer the following question:
Design an circuit with operational amplifiers that has the following output function:
Vo=2*V1+10*V2+11*V3-V4
Shoud i use the inverting adder?
Using three different voltage sorces V1,V2,V3 and V4 ,an OpAmp and a 4 resistors(R1 to R4) and a feedbak resistor.
So the expression for the output of and adding inverter is given by:
V0=-(Rf/R1)-(Rf/R2)-(Rf/R3)-(Rf/R4)
So i could use Rf=10k ,R1=5k,R2=1k,R3=1,1k and R4=10k
The problem is then Vo=-2V1-10V2-11V3-V4....Shoud i use and non-inverting adder,conecing the resistors to the non-inverting input?
Thanks
