Let's demo an inductor coil functioning as a low-pass filter. Using a signal generator and oscilloscope, we step through frequencies from 100 Hz up to 120 kHz, comparing input and output waveforms to see how inductive reactance (resistance) increases with frequency. Low frequencies pass while attenuating higher ones. Coils provide a more gradual filtering effect than capacitors, and have high-frequency “bleed-through.” Real-world filter circuits often combine inductors and capacitors for sharper cutoff. This demo is helpful for DIY electronics enthusiasts, crystal radio builders, and anyone interested in RF behavior, analog signal processing, and fundamental circuit design. Whether you're experimenting on the bench or deepening your understanding of passive components, this video delivers clear, real-world insight into how inductors shape frequency response.
