ABSTRACT:
In one aspect, the circuit has a first impedance element which preferably is in the form of a tapped inductor with a plurality of taps thereon, and a second impedance element which preferably is in the form of a capacitor. One terminal of the capacitor is connected to a terminal of the inductor, the other terminal of the capacitor is movably connected to a selected one of the taps. The circuit is tuned to a resonant frequency determined by the value of the capacitor and the value of inductance associated with the selected tap. The taps are located on the inductor to cause each resonant frequency to be a substantially fixed percentage greater than the next lower one of the resonant frequencies. In one embodiment, a connector plug is provided, having a first portion with a terminal connected to the capacitor; a second portion with terminals connected to the taps on the inductor; and a third portion matable with the second and third portions. The third portion is provided with means to cause the terminal on the first portion to be connected to a selected one of the terminals of the second portion.
