WebFeb 28, 2015 · 13th Mar, 2016. Loss factor or specific damping factor is defined as the energy dissipated per radian to the peak potential energy is the cycle. This is a very useful method to compare the damping ... WebTHE DAMPING FACTOR Rather than specify the value of R s, it has become common to translate this into a figure which is called the damping factor (DF) of the amplifier. As we have seen, it really has more to do with coupling than damping.
