Abstract

An interrogator is provided for reducing the bandwidth required for transmitting a command or control signals to a radio frequency identification transponder. The interrogator includes a carrier signal generator (RF OSC.), a modulator (10) which modulates the carrier signal with a shaped pulse envelope, and a transmitter (28) which transmits the modulated carrier signal to the transponder. The modulated carrier signal results in a reduced transmission signal bandwidth. The shaped pulse envelope may be a sinusoidal envelope, wherein the modulated carrier signal is a raised cosine modulated signal.
