varistor產生雜訊!

Pass Lab上的這篇談gound,提到

Many power strips have MOV’s and neon lights; if you are seeking the ultimate in RFI free power, do not put these devices on your entertainment system. Both devices can input a small but measurable amount of noise on the power line.

MOV應該是Metal Oxide Varistor,
我完全沒注意到會有這種效果...
