(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ВРЕМЕНИ ОТКАТА В ДИКТОФОНЕ(54) DEVICE FOR MEASURING ROLL BACK TIME IN DICTOPHONE

1one

Изобретение относитс к области накоплени информации, а именно к устройствам дл измерени времени отката в диктофонах.The invention relates to the field of accumulation of information, namely, devices for measuring rollback time in voice recorders.

Известно устройство дл измерени времени отката в диктофоне, содержащее формирователь сигнала длительности отката, подключенный к выходу диктофона 1.A device for measuring a rollback time in a voice recorder, comprising a roll back duration signal conditioner connected to the output of voice recorder 1, is known.

Известное устройство имеет относительно простую конструкцию, однако оно не позвол ет обеспечить до.статочную простоту процесса измерени времени отката в диктофоне .The known device has a relatively simple design, however, it does not allow to ensure the sufficiently simple process of measuring the rollback time in a dictaphone.

Известно также устройство дл измерени времени отката в диктофоне, содержащее формирователь сигнала длительности отката, подключенный к выходу диктофона и соединенный с первым входом коммутатора и с первым входом блока управлени , второй вход которого подсоединен к входной шине сигнала пуска, первый выход - к управл ющему входу диктофона, второй выход - к второму входу коммутатора , а третий вход - к выходу генератора временных интервалов, соединенному с третьим входом коммутатора, и индикатор 2.It is also known a device for measuring a rollback time in a voice recorder that contains a rollback duration signal conditioner connected to the voice recorder output and connected to the first input of the switch and to the first input of the control unit whose second input is connected to the start signal input bus, the first output to the control input voice recorder, the second output to the second input of the switch, and the third input to the output of the time interval generator connected to the third input of the switch, and the indicator 2.

Это устройство позвол ет обеспечить относительную простоту процесса измерени времени отката в диктофоне Недостаток его состоит в значительной погрешности измерени времени отката в дикто5 , фоне.This device allows to ensure the relative simplicity of the process of measuring the rollback time in a dictaphone. The disadvantage of it is the considerable error in measuring the rollback time in the dictophone, background.

Цель изобретени - уменьшение погрешности измерени времени отката в диктофоне.The purpose of the invention is to reduce the measurement error of the rollback time in the recorder.

Поставленна цель достигаетс за счетThe goal is achieved by

10 того, что в устройство дл измерени времени отката в диктофоне введены первый счетчик, подключенный выходом к индикатору , второй счетчик, вход которого подсоединен к выходу коммутатора, дополнительный коммутатор, соединенный первым10 that the first counter connected by the output to the indicator, the second counter whose input is connected to the output of the switch, the additional switch connected by the first are entered into the device for measuring the rollback time in the recorder.

Claims

15 INPUT with the third output of the control unit, an adder connected to the fourth input of the control unit, and a command code generator, the command code generator connected to the second input of the additional switch, the output of which is connected to the input of the adder, the third input to the output of the second counter, and the fourth input is to the fourth output of the control unit connected to the input of the first counter. The drawing shows a device for measuring the rollback time in a dictaphone. The device contains a shaper of the rollback duration signal 1, connected to the output of the voice recorder 2 and connected to the first input of the switch 3 and to the first input of the control unit 4. The second input of control unit 4 is connected to the input bus 5 of the start signal, the first output is connected to the control input of the voice recorder 1, the second input is connected to the second input of the switch 3, and the third input is connected to the generator output of 6 time slots. The output of the generator 6 time intervals connected to the third input of the switch 3. The proposed device also contains the first counter 7 connected by the output to the indicator 8, the second counter 9 whose input is connected to the output of the switch 3, the additional switch 10 and the adder 11. In this additional the switch 10 is connected to the third input of the third output of the control unit 4, and the adder 11 is connected to the fourth input of the control unit 4. The device also contains a driver code driver 12 connected to the second input of the additional switch 10, the output of which is connected to the input of the adder 11. The third input of the additional switch 10 is connected to the output of the second counter 9, and the fourth input to the fourth output of the control unit 4, connected to the input of the first counter 7. In the proposed device, the shaper 1 of the rollback duration signal converts the output from the voice recorder 2 of the playback result of the pre-recorded signal sound, frequency. When e, the volume, the switch 3 passes the generator pulses of 6 time intervals to the second counter 9. The result of counting these pulses through the additional switch 10 enters the adder 11, the signal of which is fed to the control unit 4. On the signal of the adder 11, the control unit 4 transmits pulses of the generator 6 time intervals to the first counter 7, which counts them. The result of counting by the first counter 7 is the arithmetic average of three measurements. The use of the proposed device makes it possible to significantly reduce the measurement error of the rollback time in a dictaphone. The invention The device for measuring the rollback time in a voice recorder, containing a rollback duration signal generator connected to the voice recorder output and connected to the first input of the switch and the first input of the control unit whose second input is connected to the start signal input bus, the first output to the control input voice recorder, the second output to the second input of the switch, and the third input to the output of the time interval generator connected to the third input of the switch, and the indicator, characterized in that, in order to decrease measurement error, the first counter connected by the output to the indicator, the second counter whose input is connected to the switch output, the additional switch connected by the first input to the third output of the control unit, the adder connected to the fourth input of the control unit, and the code generator are entered into it. The driver of the command code is connected to the second input of the additional switch, the output of which is connected to the input of the adder, the third input to the output of the second counter, and the fourth input to the fourth th output control unit connected to the input of the first counter.
