Claim:
1. An electrical resonant network in which at least one of a resonance frequency, an impedance and an admittance are controlled, said electrical resonance network comprising: a) at least one resonant circuit including at least one first inductor and at least one first capacitor; b) at least one reactive component; c) at least one switch controlled by at least one ON/OFF coupling signal for coupling said reactive component to at least one of said first inductor and said first capacitor, wherein said reactive component is charged and discharged by said resonant circuit and said at least one ON/OFF coupling signal alters its state at least once within a resonant circuit period; and d) a control circuit for generating said at least one ON/OFF coupling signal, wherein a first transition change in said at least one ON/OFF coupling signal is responsive to a control signal for controlling the at least one of the resonance frequency, impedance or admittance of said resonant network, and a second transition change in said at least one ON/OFF coupling signal, opposite to said first transition change in said at least one ON/OFF coupling signal is responsive to a state transition in said at least one switch.
