    摘要： A method and system for flexible radio communications using a wideband radio includes a wideband radio and multiple separable radio definition modules, wherein the wideband radio is configured to operate over a large portion of the radio-frequency (RF) spectrum and each of the radio definition modules are configured to operate in a specific frequency band. The separability of the radio definition modules maintains the capability of the wideband radio to operate over the large portion of the RF spectrum, as well as enabling its robust and reliable operation in a specific frequency band associated with the attached radio definition module.

    摘要： A differential antenna and associated control system applied to a digital television (TV). The control system includes a differential antenna receiving a broadcasting signal and generating a differential radio frequency (RF) signal including a positive signal and a negative signal; a control unit generating a selecting signal according to a selected channel; a switch circuit including a switch control circuit and a plurality of matching circuits. Each of the matching circuits optimizes part of the digital TV bandwidth, and the switch control circuit receives the selecting signal to control that an optimized positive signal is generated to the control unit after the positive signal passes through a first matching circuit of the matching circuits, and an optimized negative signal is generated to the control unit after the negative signal passes through a second matching circuit of the matching circuits. The first matching circuit and the second matching circuit optimize the same frequency band, and a differential optimizing signal includes the optimized positive signal and the optimized negative signal. Thus, the control unit generates a selected channel signal accordingly.

    摘要： A system and method to optimize the quality of a modulated signal. In one aspect, an AM demodulator is used in conjunction with proper bandwidth selection of an FM signal. For example, the AM demodulator can be used to generate an instantaneous absolute value of the FM signal. The average value of the FM signal over a period of time is subtracted from the instantaneous absolute value in order to determine a variance in amplitude in the FM signal. In another aspect, several filters may be tested and the one having the lowest variance in amplitude may be used in order to select the filter having the desirable bandwidth.
