A low delay corrector (LDC) unit includes a non-linear function generator and a filter. The nonlinear function generator receives a first signal and outputs a second signal in dependence on the first signal and a transfer function of the nonlinear function generator. The filter is fed in dependence on...http://www.google.de/patents/US7812666?utm_source=gb-gplus-sharePatent US7812666 - Low delay corrector
