steps which are done by the DSP-machine. The up sampling interpolation steps are
again processed by fast hardware structures to reduce the DSP-workload. The
upsampled 1-bit data stream is then converted to an analog equivalent which is
smoothed by a POST-Filter (POFI). At the summing point the values of the
TTX-Generator and the DC-loop are added and then transferred to the output pin 26

).
Loops
There are two different loops implemented: The Impedance Matching (IM) loop which is
divided in 3 separate loops to guarantee very high flexibility to various impedances, and
the Transhybrid Balancing (TH) loop.

DC Characteristic
The incoming information at pin IT (scaled transversal current (AC + DC) transferred to
a voltage via a resistor) is first lowpass filtered (0.3 Hz) for stability and noise reasons
and then fed into the DC-characteristic block. This consists of two branches which
represents different kinds of feeding behavior. In typical applications it acts as a
programmable constant current source (
