ABSTRACT:
A signal generator (10). The signal generator comprises circuitry (20) for producing at least a first input noise signal (N1), wherein the first input noise signal has a statistically insignificant autocorrelation. The signal generator also comprises an allpass filter circuit (40) coupled to receive and filter the first input noise signal and for outputting in response a white noise signal (50) having a Gaussian probability distribution function
