The reciter carries out signal processing and has overall control of the base
station. Its circuit boards are shown in Figure 1.5.
The receiver board contains all the receiver circuitry, while the exciter
circuitry is located on the transmit forward board.
The reciter control board converts information between analog and digital
and controls the maintainer’s access via the front panel. It performs the air
interface signal processing for digital P25 mode, gives the base station an
identity as a network element, and provides the physical connections for
the Ethernet and system interfaces.
