for small zero-ripple condition mismatches, exists where the gain peaks and attenuation
may be lost. However, the parasitic resistances damp this peak so that it is not high, even
though its effect might be visible in the waveforms, should that frequency be stimulated;
anyhow, to get the desired attenuation at the switching frequency and above, the practical
values of C
regulations do not generally apply.
A resonance frequency, close to:
