Abstract: This invention relates to a method of processing pulse like signals at the transmitter and receiver ends of a transmission medium so that the slope of the flanks of the transmitted pulses exceeds those transmittable by known methods by a medium with a limited band width. This is achieved by superposing overshoots on the pulses at the transmitter end of the transmission medium. These overshoots which have a frequency within the transmission band of the medium and consequently can be transmitted undistorted by the medium contain information about the slope of the flanks and amplitude of the original pulses at the transmitter end. These overshoots are then separated from the transmitted distorted pulses at the receiver end and a reshaping of the pulses is accomplished upon which frequency components are obtained from the overshoots, the amplitude and the time- and phase position of which have such values that the frequency components together with the transmitted distorted pulses form new pulses which well conform to the original pulses.
