Per rilevare la condizione di occupazione di un tratto di binario (B) nell'associato circuito di binario vengono generati messaggi digitali di tipo seriale con una parola formata ad esempio da 4 bit in sequenza, pseudocasuale che determinano l'emissione di corrispondenti frequenze che si succedono in modo pseudocasuale.(Figura 1)To detect the occupation condition of a section of track (B) in the associated track circuit, serial digital messages are generated with a word formed for example by 4 bits in sequence, pseudorandom which determine the emission of corresponding frequencies that they happen in a pseudorandom way. (Figure 1)
