A method for controlling signal decay of a transmitted signal within a
transmitter is described. The method includes measuring an amount of
current induced back into the transmitter by the decaying signal, and
using the current measurement to control the decay of the signal after
the signal is transmitted from the load. A transmitter for an electronic
article surveillance (EAS) system is also described which includes a
current sensing circuit configured to at least sense an amount of current
induced back into the transmitter by the load after transmission of the
signal, and a transmitter control circuit configured to utilize the
sensed current to determine an amount and a polarity of current to be
applied to the load to reduce the induced current to a desired value.
