This is a high-pass filter implemented using a resistor and an inductor. The inductor passes lower frequencies, resulting in a lower voltage across it and keeping the output voltage closer to ground. The inductor blocks higher frequencies, causing the current through the resistor to decrease and keeping the output voltage closer to the input voltage. Below the circuit is the frequency response in dB over a range of frequencies. You can click on the frequency-response graph to see the circuit operating at that specific frequency.
This page is a utility for simulating фильтр высоких частот (rl) online with specified initial values.
