Abstract:

A random state generator to determine a random non-return to zero (NRZ) vage level at a particular clocked time with a noise generating diode or gas tube to provide a randomly fluctuating analogue voltage. The random voltages are amplified and applied to a transformer which acts as a gate for the random voltage. The secondary of the transformer has unidirectional conducting means connected to each of the ends and so poled that by applying a positive voltage pulse to a center tap on the secondary, the unidirectional current devices are forward biased and close the gate. The output of the transformer is connected to a bistable multivibrator which is thereby slaved to the random voltage polarity applied to its input during clock time.
