It is shown how, using clocked delay systems, it is possible to translate the frequency of an applied periodic voltage. The translation can represent an increase or a decrease in frequency. Moreover, the amount of the translation can itself be made to change with time. A clocked delay system is constructed in a straight-forward manner using shift registers. The theory is tested using clock rates that change linearly with time and using clock rates that provide a linear time variation of delay. The resulting frequency translation is measured for sinusoidal, triangular and square wave inputs. The results are in good agreement with the theory. >
