Abstract
A wireless control system for use in system having a plurality of periodic noise sources includes an antenna; an RF receiver connected to the antenna for receiving RF noise from an external periodic noise source; a phase synchronization circuit connected to the RF receiver for generating a clock signal that is in phase with the external periodic noise; and a noise source control circuit connected to the phase synchronization circuit for receiving the clock signal and controlling a periodic noise source, whereby the periodic noise sources in the system are synchronized to emit their periodic noise in phase with each other.
