    Abstract: A device includes a plurality of channel-capture circuits. Each circuit may include an array of N non-linear oscillators, wherein N≧3, circularly connected to each other in series such that unidirectional signal flow occurs between the oscillators. Each circuit may be configured to capture a respective channel signal from a wideband signal containing a plurality of channel signals and convert its captured channel signal to a lower frequency. Each oscillator may include an oscillator input configured to receive an output signal from another oscillator, an oscillator output configured to provide an output for an input of another oscillator, a frequency capture input configured to receive at least a portion of the wideband signal, at least two amplifiers, and a control capacitor coupled to the output of the amplifiers. An analog-to-digital converter may be coupled to the output of each channel-capture circuit.

    Abstract: A target signal analyzer having at least one receiving antenna configured to receive the target signal, and a parallel array of oscillator rings. Each oscillator ring is operatively coupled to receive the target signal from the receiving antenna. Each oscillator ring has an odd number of at least three bistable, nonlinear oscillators circularly coupled to each other such that only one-way signal flow is allowed between the oscillators in each oscillator ring. Each of the oscillator rings is configured to oscillate and thereby produce a response signal only when the target signal frequency is within a designated frequency band. For every designated frequency band in a spectrum of interest, at least one of the oscillator rings is configured to produce a response signal.

    Abstract: A sensor system employing a plurality of nonlinear sensors utilizes a coupling network to interconnect the sensors wherein the coupling network inherently induces oscillations in the sensor system. This approach removes the need to provide bias signal generation either onboard the sensors or via a source external to the sensor.

    Abstract: A coupled non-linear sensor system is provided for sensing a non-sinusoidal time-dependent target signal. The system comprises an odd number, other than one, of interconnected oscillatory sensors for sensing time-dependent changes in an external magnetic flux generated by the non-sinusoidal time-dependent target signal, the sensors coupled to each other by a coupling parameter characterized by a threshold value, so that each of the sensors oscillates in the presence of the non-sinusoidal time-dependent target signal as the coupling parameter exceeds the threshold value.
