ABSTRACT:
A random sequence of 1's and 0's is generated by detecting excursions of a random noise signal above a certain positive voltage level, below a certain negative voltage level, and into an intermediate voltage range between the positive and negative levels. A 1 bit is generated each time the random signal shifts to a value above the first level and then into the intermediate range, where it must remain long enough to coincide with a clock signal. A 0 bit is generated each time the random signal becomes more negative than the second level and then shifts back into the intermediate range and remains there long enough to coincide with one of the clock signals. A signal generated at the end of each bit signal is used to clock that bit into a shift register. The same clocking signal also causes a counter to count a predetermined number of random bit signals and then to output the information stored in the shift register to a data bus for use as a random number signal.
