| 摘要 |
This invention provides a method and circuit for separating a signal of interest from an angle modulated interfering signal in which a composite signal, including the signal of interest and the interfering signal, is used to produce first and second signals, the first signal being representative of the composite signal and the second signal being representative of the envelope of the composite signal. Selected components are removed from the second signal to produce a filtered signal. The filtered signal is mixed with the first signal, to produce an output signal including a component representative of the signal of interest having a greater spectral power density than other components of the output signal.
