Delay of time functions by means of frequency domain sampling

It is possible to obtain delays of finite duration time functions by sampling in the frequency domain. The method is applicable when the delay time is greater than the waveform duration. The method is particularly amenable to analog computer techniques, and no special equipment is required. The holding feature of these machines makes it possible to delay functions several minutes. A clear-cut error analysis can be made to ensure economical use of the equipment for the degree of accuracy required.
