    Determine the cut off frequency of any filter formed from output impedance and input impedance

    Say you have a piece of electronic equipment which has an input impedance of 1Megohms, and an input capacitance of 10 picofarads as determined by a ceramic capacitor across the input resistor. This obviously creates an RC impedance filter which will act on any AC entering the device. Now enter...
