Here, a special algorithm is
presented that can compensate for the nonlinear behavior of
transformers, solenoids, and other nonlinear components.
Especially power audio amplifiers suffer from such distortions,
which are characterized by the appearance of new components in
the harmonic spectrum. To compensate for these nonlinearities in
the signal chain, the NLPD method is a worthwhile approach.
The algorithm is based on formerly
done messurements and equation optimization.
The method presented here
introduces an automatic control of the equalization and is a
further development of the static version. See
DSP-approach this system is running in an FPGA giving the option
to optimize the equation in real time.
