An apparatus for deactivating a resonant circuit without physically contacting the resonant circuit. The EAS system includes a numerically controlled oscillator for generating an alternating electric signal, the frequency of the alternating electric signal varying in accordance with a numerical frequency control signal; a clock having a substantially fixed frequency connected to the numerically controlled oscillator; and a transmitting antenna connected to the numerically controlled oscillator for establishing an electromagnetic field within a deactivation zone. The frequency of the alternating electric signal is restricted to being an integer multiple of an integer sub-multiple of the clock frequency.

The linear algorithm described differs from other artificial intelligence ograms in its operation over a continuous representation. In the algorithm, the size of the exponent is tied to the magnitude of the learning base employed, and the design thus becomes more selective as the learning base grows. With it, "run time" and "chip size" can be analyzed in substantially linear time.

An apparatus for measuring electrical characteristics of a resonant circuit without physically contacting the resonant circuit. The EAS system includes a numerically controlled oscillator for generating an alternating electric signal, the frequency of the alternating electric signal varying in accordance with a numerical frequency control signal; a transmitting antenna connected to the numerically controlled oscillator for establishing an electromagnetic field within a measurement zone; a receiving antenna for sensing disturbances to the electromagnetic field within the measurement zone; a receiver for receiving signals from the receiving antenna representative of disturbances to the electromagnetic field and for determining the Q and center frequency of the resonant circuit; and a clock having a substantially fixed frequency connected to the numerically controlled oscillator. The frequency of the alternating electric signal is restricted to being an integer multiple of an integer sub-multiple of the clock frequency.
