    In the presence of 1/f β noise, we investigate the logical stochastic resonance (LSR) in an asymmetric bistable model driven by various cycling combinations of two logic inputs. The probability of correct logic outputs is calculated according to true table of logic relationships. Two major results are presented. Firstly, it is shown that the LSR effect can be obtained by changing noise strength. Over entire range of noise variance, white noise can be considered to be better than 1/f noise or 1/f 2 noise to obtain clean logic operation. At a smaller noise level, 1/f noise can realize higher output probability than white noise or 1/f 2 noise. In the sense, 1/f noise can be considered to be better than white noise or 1/f 2 . On the other hand, the correct probability can evolves nonmonotonically as noise exponent β increases, and a kind of SR-like effect can be obtained as a result of β. At certain intermediate noise variance, the output probability is able to attain its minimum at β=1. It is also shown that actually some finite β sometime can be better than β=0 at small range of noise variance. The study might provide some potential complement to LSR effect in the presence of 1/f β noise. Copyright EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg 2011
