A high frequency signal is periodically applied to one each of a plurality of variable delay lines which receive and store respective portions of the high frequency signal. While one line is receiving and storing a high frequency signal portion the other previously stored portions are retrieved substantially simultaneously from the other delay lines, with the other delay lines operating in a low speed mode. The high frequency signal is thus continuously converted into a multiplicity of related signals each of lower bandwidth. The sequence is reversed for reconstruction of the original high frequency signal.
