Abstract
A multiplier circuit arrangement comprises two parallel paths for the same signal, one of the paths being associated with signal level adjusting means; and means responsive to inbalance of d.c. components including any in said parallel paths, the inbalance being in accordance with a d.c. signal in a third signal path, to produce a control signal for varying the signal level adjusting means to reduce the imbalance, so that a.c. components in said parallel paths will be unbalanced to an extent proportional to the d.c. signal in said third path.
