A method of time delay generation is described that is not dependent on a Pade or similar approximation. It is shown that the use of a serial analogue to digital conversion technique known as Delta Modulation can result in a simple and low cost alternative to the parallel conversion methods normally applied and it is stated that the time delay system described can be used on a low cost analogue computer with the addition of only one shift register.
