Design and test a two input circuit with following characteristics:
Vout=3.5v1 +(-1.5)v2 . The input impedances should be: input 1: 20k, input 2:∞.Youmay need to use 2 or more op-amps (inverting, noninverting,summing, differential, voltage follower...). Show calculations anda drawing of the op amps used.
