A system for transmission of continuous signals wherein the signals are sampled into sections, which sections are subsequently assembled into groups. A frequency band is permanently associated with each section dependent upon its position within the group and for each section an alternating-current pulse is produced, the frequency of said alternating-current pulse being within the frequency band associated with said section and which contains the signal contents of the corresponding section. The alternating-current pulses are longer than the sections and are temporarily overlapping one another.
