They can be used to demodulate a signal, recover a signal from a noisy communication channel, generate a stable frequency at multiples of an input frequency ( frequency synthesis ), or distribute precisely timed clock pulses in digital logic circuits such as microprocessors.

In the case of the Hewlett-UCLA work, researchers have successfully created digital logic circuits, but not yet any in which the molecular switches can be restored to their original state _ returning to the off position, for example, after having switched to on.
