Abstract
A random digital signal generator circuit responsive to a clock signal from a block signal source for outputting a sequential series of logic signals. The circuit comprises a clocked flip-flop that provides a signal at its output terminal that has a value corresponding to the state of its input signal until a subsequent clock signal is received. An array of oscillator signal generators is provided with each oscillator signal generator operating at a different frequency. An EXCLUSIVE-OR network means having an array of input terminals has each input terminal of the EXCLUSIVE-OR network coupled to the output terminal of a corresponding oscillator signal generator. The EXCLUSIVE-OR network provides a random output signal at its output terminal. The EXCLUSIVE-OR network means output terminal is coupled to the flip-flop input terminal. The flip-flop responds to each the clock signal to sample the state of the random output signal from the EXCLUSIVE-OR network. The flip-flop stores and couples the state of the random output signal to the flip-flop output terminal with each successive clock signal.
