A random number generating system operates to generate an output number bit sequence based on an entropy estimation of a true random number bit sequence, the randomness of the output number bit being an improvement of the randomness of the true random number bit sequence. A physical random number generator communicates the true random number bit sequence to an entropy estimator, which generates an estimation signal indicative of the randomness of the true random number bit sequence. The estimation signal is communicated to a decimator whereby, in accordance with estimation signal, the decimator generates the output number bit as a representation of a decimation of a mixing of the true random number bit sequence and the pseudo random number bit sequence, or as a representation of a decimation of the pseudo random number bit sequence when the pseudo random number bit sequence is generated as a function of the true random number bit sequence.
