    摘要: A device for optimizing antenna operation comprises a wireless control signal detector for detecting a wireless control signal generated by a remote control unit, and a microprocessor operatively connected to the detector. The microprocessor is programmed to analyze the wireless control signal during a learning operation to determine a coding format of the wireless control signal and to analyze the wireless control signal during a normal use operation to determine a broadcast channel or station selected by a user. The device additionally comprises a plurality of tuning elements operatively connectable to an antenna for tuning the antenna, and a plurality of switching circuits operatively connected to the tuning elements and to the microprocessor. The switching circuits are operable to selectively couple the tuning elements to the antenna, in response to signals from the microprocessor, thereby optimizing signal reception by the antenna for a channel or station selection encoded in the wireless control signal.

    摘要: A system is provided which transmits either analog or digital data signals over the air. The system includes a transmitter and a receiver. The transmitter and receiver are arranged to transmit signals using a carrier signal having a high frequency such as in the range of 902-928 MHz. The transmitter and receiver are configured to provide for the transmission of two channels of stereophonic signals while maintaining high signal-to-noise ratios, good frequency response, and low distortion. To provide for the proper transmission of signals between transmitter 10 and receiver 12, these devices include oscillating circuits having ceramic resonators which provide a base frequency which is readily modulated to facilitate proper transmission of either analog or digital signals between the transmitter and receiver. To further improve the transmission capability between the transmitter and receiver, the transmitter and receiver both include substantial buffering, isolation and shielding between selected circuit components to prevent unwanted areas of frequency modulation within the transmitter and receiver.
