3. A high-pass filter is a circuit that lets high- frequency signals pass with ease but virtually eliminates low-frequency signals. Consider the RL high-pass filter shown below. a) If a voltage Vin = Vo sinwt is put across the gap ab, what current will run from a through the two resistors and inductor to b? b) What voltage will be read across leads cd (Vout)? R c) Find the ratio of the amplitudes of the two voltages Vo,out/Vo,in. Vin Vout d) At what frequency will the strength of the outgoing signal be only half of the incoming signal? e) Replace the inductor with a capacitor C and repeat parts (a) through (d). What type of filter is this? *
