Design an op-amp circuit that meets the following specifications. Your design can be done with one or two op amps.
Important: Show all work. Draw a completely labeled schematic of your design that shows the exact values of all components.
a. The op-amp circuit must have an adjustable, non-inverting overall voltage gain from +2 to +10. The circuit has a 47 kΩ load resistor connected from the last op amp’s output terminal to ground.
b. The circuit input resistance must be 50 kΩ.
c. Your design is limited to a maximum of two op-amps and seven resistors, one of which is a variable 50 kΩ resistor (potentiometer). The potentiometer resistance is 0 when adjusted to one extreme of its range and 50 kΩ at the other extreme.
d. When the potentiometer is adjusted to one extreme position the overall circuit voltage gain should be +2. When the variable resistor is adjusted to its other extreme position the overall circuit voltage gain should be +10.
