Design and set up a circuit using basic op-amp configuration that will implement a mathematical expression Y = 3A-2B-C (where A, B, and C are the inputs and Y is the out of the circuit). Then verify the design for A = 3V, B = 1V, and C = -2V. (Hint: Generate these input voltages from a 5V DC source). Use resistor values of the order of 100K ohms for the feedback and input resistors in the op-amp circuit. Note:...

Assume the op-amp below is used as a comparator circuit and that
the op-amp is powered by a bipolar
+/- 15 V power supply. If the reference voltage Vref = -9 V and the
input voltage is VI = 12 V,
determine the output voltage, VO, of the op-amp. Assume the
open-loop gain, A, is very large and
consider saturation effects. Include units in your answer.
