Abstract
A random number generator generates a string of random bits from a received RF signal source. A sample-and-hold circuit is coupled to the received RF signal source. The RF signal is sampled by a jittered clock signal from a source coupled to the sample-and-hold circuit. The frequency of the jittered clock signal is less than frequency of the received RF signal. The random number appears at the output of the sample-and-hold circuit.
