Question

8. Two signal sources have internal voltages $v_1(t)$ and $v_2(t)$, respectively. The internal resistances of the sources are known always to be less than 1 Kohms, but the exact values are not known and are likely to change over time. Desing an amplifier for which the output voltage is $v_o(t) = A_1v_1(t) +$ $A_2v_2(t)$. The gains are to be $A_1 = 5$ and $A_2 = -2$. Assume that ideal ops are available.

8. Two signal sources have internal voltages v(t) and v2(t), respectively. The internal resistances of the sources are known always to be less than 1 kΩ, but the exact values are not known and are likely to change over time. Design an amplifier for which the output voltage is vo(t) = A1v(t) + A2v2(t). The gains are to be A1 = 5 and A2 = -2. Assume that ideal op-amps are available. R1 = 0-1kΩ R2 = 0-1kΩ RB = M
