ABSTRACT:
Method for the conversion of a frequency into a number, characterized in t use is made of a reversible counter driven by a logic control circuit receiving clock pulses and a frequential input signal formed by pulses having a period of a in addition to a stochastic feedback signal representing the required number, where the required number is a number which depends on the frequency of the input signal and is generated by this method. The logic control circuit makes the counter count up the clock pulses during the time periods a and makes it count down the pulses of the stochastic signal during all other times. The stochastic signal stored in the reversible counter represents a number which depends on the frequency of the frequential input signal being sampled.
