A resistor and capacitor are in series. The signal is at 3 herts and a passive filter must be used to remove a 60hz noise with -10db attenuation. The resistor is 100 Ohms. HOw do you find the capacitance, ive been tryin it for an hour. Usually you would find it with the corner frequency but this question wants us to find the corner frequency using the capacitance. Please helppp!! Is the corner frequency just the frequency of the signal?
