An analog signal is processed through a lowpass filter and then regularly sampled at different sample times by a plurality of charge coupled devices. The outputs of the charge coupled devices are then summed and applied to a second lowpass filter which acts to produce a reconstructed and delayed version of the original analog signal. With this arrangement the time delay associated with each charge cell of the charge coupled devices is a whole number multiple of the effective sampling period of the system, and significant decreases in charge transfer distortion are achieved.
