Abstract
A circuit arrangement for the analogue suppression of echoes, as in particular can be used in a hybrid-circuit for DSL-transmission systems, comprises a replica () for emulating the behaviour of the transmission line (). In addition, a circuit () for emulating the behaviour of the transmitter () is provided, which comprises at least one lowpass (). Furthermore, a replica () for emulating the behaviour of bridge taps () can also be provided, which comprises at least one bandpass (). Additionally, a replica () for emulating the behaviour of the line driver () can also be provided.
