1. A method of blocking noise in radio links for digital data transmission, based on the sending of information on logical states in the time interval between the changes of states at the output of the demodulator of the receiver, on emission of an unmodulated carrying wave before data transmission, and on blocking of the output of the circuit following completion of data transmission, characterized in that the moments of logical state change at the output of the demodulator of the receiver are determined, and then a measurement is made of the time between particular state changes, while the output of the circuit is blocked when that time is less than the time of transmission of the unmodulated carrier wave which precedes data transmission, but if that time is equal to or greater than the time of transmission of the unmodulated carrier wave which precedes data transmission, then the output of the circuit is unblocked.<IMAGE>
