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.

摘要： A method for processing electrical signals includes the steps of: storing a plurality of first data signals, each representative of an instantaneous amplitude of a first input signal in a memory; selecting one of the first data signals in response to a second input signal; combining the selected one of the first data signals with a second data signal representative of a subsequent instantaneous amplitude of the first input signal, to produce a difference signal; producing a first output signal in response to the difference signal; and combining the difference signal and the selected first data signal to produce a modified data signal and for replacing the selected one of the first data signals with the modified data signal in the memory. The method can be performed by an equalizer in a circuit for compensating for amplitude variations in a radio frequency signal or by a comb notch filter. The invention also encompasses circuits and combinations of such circuits which perform the above signal processing method.

摘要： A magnetic sensor assembly (S) of the type having at least one capacitor (44) electrically connecting an output signal (70) from a magnetic sensor unit (24) to an output signal source (30) includes switch (14) for controllably electrically disconnecting the capacitor (44) from output signal (70) and alternatively connecting the capacitor (44). The capacitor (44) is disconnected from the magnetic sensor unit (24) by the switch (14) during times that transient signals may be generated by the magnetic sensor unit (24) thereby preventing the capacitor (44) from being charged. A magnetic sensor assembly (100) uses printed circuit boards (PCB) (102) having a conductive element (106) on or within the PCB (102) beneath a magnetic sensor element (104) for testing.

摘要： This invention provides a method and circuit for separating a signal of interest from a composite signal including a signal of interest and an angle modulated interfering signal, in which an in-phase component of a reference signal representative of a composite signal is mixed with the composite signal to produce a first compound signal, selected components from the first compound signal are removed to produce a first filtered signal, and the in-phase component of the reference signal is mixed with the first filtered signal to produce a second compound signal. Similarly, a quadrature component of the reference signal is mixed with the composite signal to produce a third compound signal, selected components from the third compound signal are removed to produce a second filtered signal, and the quadrature component of the reference signal is mixed with the second filtered signal to produce a fourth compound signal. The second and fourth compound signal are combined to produce an output signal in which the spectral power density of the signal of interest is greater than the spectral power density of the interfering signal. In an alternative embodiment, the reference signal may be derived from either a the first or third compound signal or both. The reference signal may alternatively be representative of the interfering signal.
