Ripple
Türkçe: Ripple (çıkış dalgalanması)
The small alternating voltage superimposed on a DC output, caused by switching and mains frequency.
// EXPLANATION
Ripple is measured in mV peak-to-peak. High ripple shortens capacitor life and upsets chip stability. In quality power supplies it is kept well below ATX limits (120 mV on the 12 V rail).
