You need to build a circuit with a resistance of 2000 ohms. All you have at hand are several 4000 ohm resistors. You should:

1.

Connect two 4000 ohm resistors in parallel.
2.

Connect four 4000 ohm resistors in parallel.
3.

Use one 4000 ohm resistor and change the voltage used.
4.

The circuit can't be built with what you have, and you'll have to order some new electrical parts.

Part 1: I need to design a circuit using only resistors and capacitors that will filter out a signal above a specific frequency. In order to be deemed a success, the peak voltage across your capacitor must be equal to 20% of the peak voltage provided by the function generator at the frequency f_theory. Full credit on this lab requires that your percent error in Part 2 is less than 5%. f theory = 1699Hz Available values of resistance are...
