  • System for filtering signals of high and low frequency bands, and relevant implementation device
    Patent number: 5311157
    Abstract: A filtering system for separating a composite signal containing two signals in different frequency bands: a high frequency signal and a low frequency signal. The composite signal to be separated is input into an inductive element in a high frequency filter section. The high frequency signal is immediately coupled by mutual induction with a resonant element of the high frequency filter section, the resonant element being designed so that the low frequency signal is not coupled because of the low value of its frequency. The low frequency signal is transmitted to low pass filter section which rejects any signal remaining in the high frequency band.
