Measuring Ripple and Noise
10106071031600 Measuring Ripple and NoiseWhile ripple and noise are generally considered interchangeable, they often represent different measurements, requiring different methods and techniques. For example, when we are discussing ripple and noise related to a switching regulator we usually mean the ripple signal that results after filtering the switched signal and the spike noise or ringing associated with the switching edges.Most systems are complicated, with the ripple and noise being generated from several different sources. Since voltage regulators also have finite and nonzero output impedance, variations in the load current result in variation of the o…
