This is a low-pass filter implemented using a resistor and an inductor. The inductor passes lower frequencies, resulting in large swings of the output voltage. Higher frequencies are blocked, and the current through the resistor decreases, keeping the output voltage closer to ground. 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 низких частот (rl) online with specified initial values.
