Smoothing factor

The smoothing factor G , also known as the absolute stabilization factor, indicates the ratio of the absolute voltage change at an input of a two-port to the absolute voltage change at the output.

${\displaystyle G={\frac {\Delta U}{\Delta U_{\mathrm {Z} }}}=1+{\frac {\Delta I_{\mathrm {Z} }}{\Delta U_{\mathrm {Z} }}}\cdot R}$

In the case of a diode with a differential resistance , this becomes: ${\displaystyle r_{\mathrm {Z} }={\frac {\Delta U_{\mathrm {Z} }}{\Delta I_{\mathrm {Z} }}}}$

${\displaystyle G=1+{\frac {R}{r_{\mathrm {Z} }}}}$.

The quality of a voltage stabilization is indicated by the smoothing factor and the stabilization factor. The greater the ratio , the better the stabilization . ${\displaystyle {\frac {R}{r_{\mathrm {Z} }}}}$
