Abstract:
A system to receive and transmit electromagnetic signals, comprising:an interface subsystem; a receiving subsystem; a transmitting subsystem; a selection subsystem; and a controller to cause said selection subsystem to couple said interface subsystem to said receiving subsystem during receiving operations, and to cause said selection subsystem to couple said interface subsystem to said transmitting subsystem during transmitting operations; wherein said receiving subsystem comprises: a gating device under the control of a first control signal that samples a first signal to generate a second signal, said first signal having a first frequency, said second signal having a second frequency, and wherein said second frequency is lower than said first frequency; and wherein said transmitting subsystem comprises: said gating device that gates a third signal according to a second control signal to create at least one desired harmonic, wherein a fourth signal is generated from at least said at least one desired harmonic.
