The remedy is to bias the transistors to about the middle of the
bottom bends, as in Fig.
19.11.
If the biasing has been well judged
the two output waveforms will add up to a very acceptable enlarged
copy of the input. The crossover region is shown inset on a larger
scale. Obviously the success of this method depends on how
accurately the biasing has been set in the first place and kept there in
spite of changes in transistor characteristics, due mainly to
temperature changes. It is not much good having a beautifully
undistorted output immediately after switching on if severe
distortion sets in when the transistors have warmed up. This
