What is Power Supply Ripple Noise – Details Explained

An AC waveform can be identified on the DC output of a S.P.S., which is shown in Figure 2.4. There are two AC components, also known as Ripple and Noise (R&N), on the DC output. The first one, coming from sine wave rectification, is at a low frequency which is 2 times of the input [...]
