Abstract
A system is provided that can automatically adjust a tuned circuit to resonate at the frequency of an applied excitation signal. The error in the resonant frequency of the tuned circuit is determined in real time from signals derived from within the network. The system permits the use of a time varying excitation frequency in a high Q circuit, including modulation conveying information. The tuning information may be stored in a memory and used to set the tuning instantaneously in order to maintain resonance when the excitation frequency changes abruptly, for example when frequency shift keying is used.
