(About the Invention about instrument making, namely, to recording devices of 1R1 of FLEX codes of rhythmic processes on a magnetic carrier. According to the main auth. No. 555427, a device of digital magnetic recording is known, containing in series a pulse shaper, a control unit, the first circuit And, the first the counter, the main circuits AND and the register connected to the recording unit, the second circuit AND, the second counter connected in series between the second code and the BTopbw input of the unit, two reference pulse generators connected to Respectively to the second inputs of the first and second circuits AND, the third and fourth outputs of the control unit are connected respectively to the second inputs of the main AND circuits and to the installation input of the first counter, and the output of the second AND circuit is connected to the additional input of the fl} register. However, the known device It is not possible to encode the temporal position of the code groups of the recorded intervals, which reduces the recording accuracy. The purpose of the invention is to improve the recording accuracy. The goal is achieved by the fact that a third And additional circuit, the third counter and the main And in the quantity are entered into the device (The third counter bits are connected respectively between the outputs of the third counter bits and the register inputs, while the additional And circuit is connected between the third output of the control unit and the second inputs of all the main circuits And, and the output of the first generator is connected to the input of the third counter and to the input of the third additional circuit And the second The device contains sequentially connected pulse driver 1, control block 2, first AND 3 circuit, first counter 4, main AND 5 circuits, register 6 connected to recording block 7, second AND 8 circuit, second counter 9 connected in series between the second input and the second output of control unit 2, two generators 10 and 11 reference pulses, connected respectively to the second inputs of the first and second circuits And 3 and 8, the third counter 12, switched on by the output of the first generator 10 reference pulses and the first inputs of IZ circuits, the third AND 13 circuit connected between the third output of control unit 2 and the second inputs of the ocHOBHbix AND 5 circuits, the second input of which is connected to the output of the first generator 10 reference pulses, while the fourth output of the control unit 2 is connected to the installation input of the first counter 4, the output of the second circuit And 8 is connected to the auxiliary input of the register 6, the input bus 14 is connected to the input of the formative 1 pulse, and the output bus 15 to the output of the recording unit 7. The device works as follows. The pulse sequence from the input bus 14 arrives at the shaper 1, from which the generated pulses arrive at the control unit 2. The control unit 2 opens the AND 3 circuits and the pulses from the generator 10 arrive at the counter 4. At the same time, the pulses from the generator 10 arrive at the counter 12, which forms the current time code sequence. At the end of the interval between pulses, control unit 2 at the third output gives an enable signal to overwrite codes in register 6. The resolving signal arrives at the AND 13 circuit and is gated with a pulse from the generator 10 in such a way that the code transfer from counters 4 and 12 through the main AND 5 V register 6 is produced at the time of the static state of the counters. After this, the signal from control unit 2 returns the counter 4 to the initial state, the AND 8 circuit opens, and the pulses from the generator 11 go to the counter 9 and the register 6, from which the output pulses go through the write block to the output bus 15. Thus, the output bus 15 will be a code sequence displaying the interval between pulses and the current measurement time. The output impulse of the counter 9 is fed to the control unit 2, in this case the AND 8 circuit is closed and does not transmit pulses from the generator 11,

processing of the next interval, namely, to study the correlation of la between pulses, of several rhythmic processes in

The use of the proposed devices for recording the structure of the signaling system allows us to significantly expand the functions formed by the proposed to fix the functional capabilities of the equipment.
