ABSTRACT:
A control circuit for maintaining the mean value of the amplitudes of control pulses having a first level and data pulses having a second level includes a detector for providing the control pulses and the data pulses. A reference voltage source provides first, second and third reference voltages having three different levels. A plurality of comparators each receive both the control pulses and the data pulses. A first comparator also receives the lowest of the reference voltages and provides regulation pulses when the control pulses reach the level of the lowest reference voltage. A second comparator receives the second highest reference voltage and provides level limiting pulses to maintain the level of the regulation pulses constant. A third of the comparators receives the highest reference voltage and provides data pulses when the third reference voltage is reached.
