TRANSMITTER UNIT FOR AN ANTI-THEFT SYSTEM IN A MOTOR VEHICLE

摘要

The invention relates to a transmitter unit comprising a sine wave generator (1) which generates a carrier wave that is modulated into binary information in a modulator (2). The modulated wave is fed to a transformer (4) which transmits the modulated wave to several parallel connected antennas (8), thereby providing a simple transmitter unit with low spurious radiation.
