Extracted text: 1. Design a weighted summing amplifier to obtain the output given below. Show your work explicitly. (Use ideal Op-Amps and appropriate resistors) (20pts) y(t)= 3V:(t)+5V2(t)+2V3(t) 2. Sketch your design using LTSPICE (or any SPICE program) and simulate it for the cases below. Use may use ideal Op-Amps (Vnppy-±15V). (30pts) a) V:(t)=5x10°Sin2000nt, V:(t)=3x10*Sin(2000nt+T), V:(t)=120x10°Cos(2000tt) b) V:(t)=Sin2000nt, V2(t)=4Sin(1000nt+1), V3(t)=10Sin(1000nt+Tt)
