Abstract
A circuit arrangement for a continuous adjustment of the base width in a stereo decoder in which a sum signal and a difference signal of two reproduction signals are obtained from a received signal and are converted by way of a matrix operating with sum and difference formation to form the reproduction signals, provides that the matrix input for the different signal is preceded by an attenuator which has a control input for receiving a control voltage and attenuates the difference signal in dependence upon the control voltage. The control voltage is dependent upon the strength of the received signal so that the difference signal component in the reproduction signals is reduced with decreasing strength of the received signal.
