Question

1. Design two circuits to produce the following output: v_O = 2_v1 -4_v2.

(a) In your first design, use a standard subtractor.

(b) In your second design, both inputs must be into high input resistance amplifiers to avoid loading.

2. Design a noninverting summer for five inputs with equal gains of 10.
