摘要： Methods and circuitry for calibrating inductive-capacitive resonant circuits are disclosed. An example of the circuitry includes an inductive-capacitive (L-C) resonant circuit operable to receive signals in response to induced electromagnetic signals transmitted on a carrier frequency. A demodulator has a signal source and is operable to demodulate signals generated by the L-C resonant circuit. Switching circuitry is operable to inject signals generated by the signal source into the L-C resonant circuit during a calibration mode. The calibration mode is for adjusting the capacitance in the L-C resonant circuit to tune the L-C resonant circuit to the carrier frequency.

摘要： The invention provides a carrier frequency offset processing method, an apparatus and a receiver. The method comprises: receiving, through a software and hardware interface, an estimated value of frequency offset of a data packet transmitted by an automatic frequency offset control module; collecting the received estimated value of frequency offset of the data packet and performing statistical analysis to obtain a statistical value of carrier frequency offset between a receiving module and a transmitting module; and dynamically adjusting, according to the statistical value of carrier frequency offset, a bandwidth of a low-pass filter through the software and hardware interface. The invention realizes dynamic adjustment of the bandwidth of the low-pass filter in the process of a receiver receiving signals, solving the problem of the impact on processing performance brought by the fixed bandwidth of a low-pass filter in the prior art.

摘要： A method of performing alternate frequency switching in a radio includes tuning the radio to a primary frequency. A candidate alternate frequency is identified. It is determined whether the candidate alternate frequency is a third order inter-modulation artifact. Tuning is switched from the primary frequency to the candidate alternate frequency only if it is determined in the determining step that the candidate alternate frequency is not a third order inter-modulation artifact.

In one embodiment, the interactive audio system comprises a processor and a receiving module for receiving a radio frequency (RF) carrier signal associated with a broadcast station. The audio system further comprises a memory storing computer-executable instructions, where the processing module is configured to access and execute the computer-executable instructions to perform a set of acts. The acts include shifting a frequency associated with the received RF carrier signal to an intermediate frequency (IF). The acts include demodulating the frequency shifted portion of the RF carrier signal associated with the broadcast station, the demodulation resulting in an output signal. The acts further include extracting an embedded data from the demodulated output signal, where the embedded data can be utilized to interact with a party associated the embedded data. The acts further include serving the embedded data in conjunction with the demodulated audio signal.
