Conclusions
In weak-signal converter circuits with germanium transistors it is advisable to use double-pole control, since this increases the conversion coefficient, whereas the zero level drift is virtually independent of the switching method. In converter circuits with silicon transistors single-pole control should be used, since this reduces substantially the zero level, whereas the conversion coefficient does not change.
