Figure 20-21 Analog Frontend Interface - Block Diagram
For each direction, an amplifier is provided for level adjustment. The signal coming from
the analog front end is passed through a high-pass (HP). With the parameter HP, the
high-pass can be configured either to suppress the DC part of its input or to be a "real"
high-pass with the -3 dB corner frequency at 180 Hz. Furthermore, up to three signals
can be mixed in order to generate the outgoing signals (S
associated registers.
