    • The present invention relates to a method for tuning a radio filter. The filter comprises an input connection, an output connection and at least two resonator modules coupled in cascade, each having a tuning mechanism and a probe. A first resonator module is connected to the input connection and a final resonator module is connected to the output connection. The filter is adapted to receive at least one signal within a frequency range. The method comprises essentially two steps: coarse tuning, which is dependent on the frequency content of the received signal(s), and fine tuning, which is dependent on a calculated deviation between a set value vector and a measured signal parameter vector. A relationship between the set value vector and the signal parameter vector is established for calculating the deviation. The invention also relates to a radio filter and a system comprising such a radio filter.

    • The present invention relates to a method for detecting tones in a received signal, whereby the signal is non-uniformly sampled at a rate below the Nyquist frequency. The method comprises the steps of : - finding a peak in the frequency spectrum of the received signal, - estimating the frequency of that peak, - estimating the complex amplitude of the peak by solving an optimization problem wherein frequency leakage due to the peak at the estimated frequency is minimized, - eliminating from the received signal the tone with the estimated frequency and complex amplitude corresponding to the peak, yielding a modified received signal, - performing the previous steps on the modified received signal.

    • A receiver wherein a received signal inputted to an RF amplifier (3) is attenuated by an attenuating circuit (10), and a frequency band is detected in which the field strength of the attenuated signal is greater than a predetermined level. The attenuation of the received signal utilizes the tuning voltage of a local oscillator circuit (5) that increases with increasing received frequency and decreases with decreasing received frequency, thereby causing large currents to flow through diodes (D1,D2) to reduce the ON-resistance and increase the attenuation amount of the received signal for a higher frequency range, while causing small currents to flow through the diodes (D1,D2) to increase the ON-resistance and reduce the attenuation amount of the received signal for a lower frequency range. In this way, the difference in signal attenuation amount due to different received frequencies can be reduced.
    • 一种接收器,其中输入到RF放大器(3)的接收信号被衰减电路(10)衰减,并且检测到其中衰减信号的场强大于预定电平的频带。 接收信号的衰减利用随着接收频率的增加而增加的本地振荡器电路(5)的调谐电压,随着接收频率的降低而减小,从而使大电流流过二极管(D1,D2)以降低导通电阻 并且在较高频率范围内增加接收信号的衰减量,同时使小电流流过二极管(D1,D2),以增加导通电阻并降低接收信号在较低频率范围内的衰减量。 以这种方式,可以减少由于不同接收频率引起的信号衰减量的差异。
