Results of analytical model and numerical simulations. Top: Example of a discrete signal consisting of a correlated bipolar string with p(s t = s t+1) = 0.7. Bottom: Comparison of different objective functions versus noise intensity for correlated bipolar strings with symmetric threshold and a signal-to-threshold distance of 0.1. Analytical and numerical solutions coincide, and all objectives functions show a maximum at the same noise level. MI = mutual information, AC = autocorrelation of the output signal.
