Question 1818 TCO 2 In a scaling adder Points 7 the input r

Question 18.18. (TCO 2) In a scaling adder, (Points : 7)

       the input resistors are all the same value.
       the input resistors are all different values.
       the input resistors have values that depend on the assigned weight of each input.
       the ratio R_f/R must be the same for each input.

Question 19.19. (TCO 2) What is the output waveform of an ideal difference amplifier with identical sine waves that are in phase on its two inputs? (Points : 7)

       Dc level
       Sine wave with ½ x amplitude
       Sine wave with 2 x amplitude
       Sine wave with 2 x frequency

Question 18.18. (TCO 2) In a scaling adder, (Points : 7)

18.The input resistors have values that depend on the assigned weight of each input.Hence it is also called as weighted amplifier.

Vo=-[(Rf/Ra)Va+(Rf/Rb)Vb+(Rf/Rc)Vc]

19. Vo=A(V1-V2)

***If V1=V2 then Vo=0(dc level)

If suppose V1=5*sint,V2=2*sint; then Vo=3*sint (i.e sine wave)
