Abstract
A circuit for processing an input pulse signal of which the slew rate is dependent on pulse frequency comprises an amplifier (30; 78) for receiving the input pulse signal and generating an output pulse signal having transitions of which the slew rate is dependent on a bias current supplied to the amplifier, and a circuit (38-66; 82-108) for supplying bias current to the amplifier, the bias current being representative at least substantially of the frequency of occurrence of pulses in the input pulse signal.
