ABSTRACT:
For the conversion of a signal read from a record carrier into a rectangular signal, a threshold-value circuit is used, whose threshold value is determined by a reference signal. The reference signal is derived from a d.c. component in the converted signal. During a dropout in the signal being read, the reference signal is maintained at the level which it had before the occurrence of the dropout.
