Low pass Filter Systems.

  1. Nov 4, 2013 #1
    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?

    Welcome to the PF.

    What is the equation for the LPF transfer function? Vo/Vi = ???

    You want to pass 3Hz and attenuate 60Hz by 10dB. Use the transfer function equation to figure out the value of C...
