1. A filtered cascaded synchronized nonlinear system comprising:

  • a nonlinear transmitter comprising;

    stable first and second subsystems, said first subsystem producing a first transmitter signal for driving said second subsystem, and said second subsystem producing a second transmitter signal for driving said first subsystem;

    first means for filtering the second transmitter signal to produce a filter output signal; and

    second means responsive to the second transmitter signal and the filter output signal for producing a transmitter output signal; and

    a nonlinear cascaded receiver comprising;

    third and fourth cascaded subsystems being respective duplicates of said first and second subsystems;

    third means responsive to the transmitter output signal from said second means and to a receiver filter output signal for producing a first receiver drive signal to drive said third subsystem to produce a first receiver signal in synchronization with the first transmitter signal to drive said fourth subsystem;

    said fourth subsystem being responsive to the first receiver signal for producing a second receiver signal in synchronization with the second transmitter signal; and

    fourth means responsive to said second receiver signal for producing the receiver filter output signal.
