Quest Scientific - Hum Bug Noise EliminatorSimple 50/60 Hz sine waves. Mixture of 50/60 Hz harmonics. Noise spikes from dimmers. Complex noise from fluorescent lamps. No DC voltage shift. The Hum Bug solves these problems. TRADITIONAL APPROACH: Faraday cages decrease the magnitude of environmental noise sources but this protection is often incomplete and working within a cage can be cumbersome. Notch or comb filters are occasionally used to suppress 50/60 Hz noise and harmonics but these filters will distort the input waveform if frequency co...
