    摘要： A receiver system and method are disclosed for processing multipath propagated signals and multiband signals. The receiver includes a zero-intermediate frequency converter for demodulating one of the plurality of multipath propagated signals to produce a demodulated signal; and a sampling module for sampling the demodulated signal.

    摘要： In a filter comprising a plurality of cavities coupled to each other by means of metal probes, the cavities have respective tuning rods which extend therein and whose cross-sectional area is not constant throughout the whole of their length, so that the filter bandwidth is made fairly constant within a large range of tuning frequencies.
