    I have to design and simulate a circuit on multisim and I don't have a clue on how to go about it. I need to design a circuit below that will accept a signal in a range from 10kΩ to 100kΩ and output a voltage ranging from 0V to +5V. I know I'm going to need some op. amp. circuits, but from there I'm lost.

    Hi,

    We're lost, too. What's the nature of the signal? The 10K - 100K you state is just the input resistance of the signal processing device. Does the signal need amplification, and, if so, by how much?

    An op amp and three resistors may do the trick, but we need more information.

    Signals are not measured in ohms.

    Hi,

    Are you saying that an increase in resistance sensed at the input of the circuit must result in a proportional increase in the output voltage?
