Abstract
The invention relates to a device and method of reducing the cross-talk between a data signal (HF) and an input push-pull signal (PP), for generating an output push-pull signal (IPP), said method comprising: -a convolution step for convoluting said data signal (HF) with a filter (F), for generating a first intermediary signal, -a multiplication step for multiplying said first intermediary signal to an adaptive scaling factor (a), for generating a second intermediary signal, -a subtracting step for subtracting said second intermediary signal to said input push-pull signal (PP), for generating said output push-pull signal (IPP). Use: Optical recording

Method of reducing the cross-talk between a data signal (HF) and an input push-pull signal (PP), for generating an output push-pull signal (IPP), said method comprising:
- a convolution step for convoluting said data signal (HF) with a filter (F), for generating a first intermediary signal,
- a multiplication step for multiplying said first intermediary signal to an adaptive scaling factor (α), for generating a second intermediary signal,
- a subtracting step for subtracting said second intermediary signal to said input push-pull signal (PP), for generating said output push-pull signal (IPP).
Device for reducing the cross-talk between a data signal (HF) and an input push-pull signal (PP), for generating an output push-pull signal (IPP), said method comprising:
- convolution means for convoluting said data signal (HF) with a filter (F), for generating a first intermediary signal,
- multiplication means for multiplying said first intermediary signal to an adaptive scaling factor (α), for generating a second intermediary signal,
- subtracting means for subtracting said second intermediary signal to said input push-pull signal (PP), for generating said output push-pull signal (IPP).
