ABSTRACT:
A communication circuit designed to be coupled to a radio receiver so as to receive a data signal and a receive signal strength indicator signal indicative of radio carrier strength therefrom, and further designed to be coupled to a controller, the communications circuit including a first, second, third, and fourth subcircuit. The first subcircuit receives the receive signal strength indicator from the receiver, determines radio carrier strength therefrom, and transfers the determined strength information to the controller. The second subcircuit receives the data signal from the receiver, determines if there are bit error within that signal, and transfers its determinations to the controller. The third subcircuit receives the data signal from the receiver, determines if there is jitter therein, and transfers its determinations to the controller. The fourth subcircuit is coupled to the second and third subcircuits to receive the output thereof, and is further coupled to the controller so as to receive output therefrom, the fourth subcircuit acting in response to the outputs to suppress signal noise.
