Bell's inequalities and EPR—Bohm correlations: working classical radiofrequency model

A description is given of an electron model which makes it possible to simulate pair correlation of random dichotomous signals of the Einstein—Podolsky—Rosen (EPR) type in the Bohm variant. This model can be used to demonstrate that Bell's inequality is satisfied in classical physics. Some features of parametric rf oscillators are used in the model. An analysis of the operation of the model helps one to understand the difference between quantum and classical correlations in EPR experiments. A specific mechanism is suggested for 'nonlocal' control of EPR-type correlations between distant observers, which applies to classical and quantum models. A controlled correlation between two random telegraphic signals is ensured by transmission, to two observers, of a sequence of pulses with the same random phase. An elementary derivation of Bell's inequality is given and an analysis is made of the logic of the use of the popular term 'quantum nonlocality' employed usually in the description of the quantum variants of the investigated experiment.
