ABSTRACT:
A signal combining circuit for adaptively combining first and second signals includes a comparator to develop a control signal to indicate when the combination of the first and second signals will have an amplitude exceeding a predetermined amplitude in one polarity sense. In the absence of the control signal the first and second signals are combined. On the occurrence of the control signal the first signal is combined with a further signal related to the first signal and a reference value.
