1. The problem statement, all variables and given/known data The schematic shows a low-pass filter identical to the one you built in studio. This filter uses a 60 k resistor and a 250 pF capacitor, and the input signal is at 30 kHz. (1 pF=10−12 F). http://loncapa.mines.edu/res/csm/csmphyslib/P200_Materials/TestBank/AC_Circuits/LowPassFilter.jpg [Broken] What is the signal gain? Remember, gain means the ratio of the output voltage (the voltage across some indicated component) to the input voltage (the voltage of the power supply). 2. Relevant equations ??? 3. The attempt at a solution Nothing we've ever learned lets us compare voltage without knowing current. If it helps, the reactance is 2.12×104 Ohm. I can't use V=IZ, C=Q/V, everything equation we've been taught can not be used because we're missing information.
