1. An electronic circuit for amplifying and synchronizing a random analog input noise signal having a statistical characteristic to produce a useful random data digital signal, the digital signal having statistical characteristics essentially the same as the characteristics of the random analog signal, the circuit comprising:

  • a system clock signal input;

    first integrator means connected to said input for generating a first integrated signal from a system clock signal applied to said input;

    a second integrator means connected to said input for generating a second integrated signal utilizing the system clock signal and for generating the random data digital signal at an output thereof;

    both integrator means being clocked at the same rate;

    means for comparing said first and second integrated signals and for generating an output of said comparing means responsive to said comparison, said output of said comparing means being a second input of said second bias means; and

    means for applying a time varying noise signal in superposition with said first integrated signal.
