Feedback to feedforward transformation for modelling operation of feedback amplifiers

摘要

The method involves opening the feedback path in the real system and model and modelling the input (11) separated from the feedback path so that the situation for each component not in the feedback loop hardly varies. The model feedback network (30) is operated so that the situation for the feedback path is similar to that in the real system. The feedback network can also be separated from the output, which can be modelled to be similar to the output (21) of the modelled system
