Fig. 3.1 Block diagram of the transmitter
Orders from the push buttons are picked up by the microprocessor, which draws up the FFSK signal
adding direction and control codes, and injects it to the UHF transmitter This transmitter incorporates
the signal of this order to the carrier frequency, which after filtering, will be transmitted by the
antenna.
In GCFI equipments, the transmitter becomes a transceiver. This enables a bidirectional
communication with the receiver.
