Eric Brotto Eric Brotto 36. To build a high pass RL filter, the inductor is placed in parallel to the power source signals entering the circuit, as shown below in the following circuit: Hallgrim Hallgrim 11.

Low Pass RC Filter A Low pass RC filter, again, is a filter circuit composed of a resistor and capacitor which passes through low-frequency signals, while blocking high frequency signals.
A sinc filter is better. Recommended Course. Inductive reactance is how the impedance, or resistance, of the inductor changes based on the frequency of the signal passing through the inductor.

Note that the example is extremely simplified. It passes through high frequencies but block low frequencies.Basic Low Pass and High Pass Filters
Being that a capacitor represents a low resistance in a circuit for high-frequency signals, they will take the path through the capacitor, while low-frequency signals will take an alternative, lower-resistance path.
This can have very useful tonal results. In high-pass, you try to remove low frequencies.
