Description

The invention relates to computing and can be used to record continuous analog signals. Information recording devices are known that contain a switch, an analog-code converter, an accurate perforator, a synchronization unit, the outputs of which are connected to the corresponding inputs of a serially connected switch, an analog-code converter, and a tape perforator 1. The closest in technical essence to the present invention is a device for recording information, comprising a switch, a digital measuring device, a perforator control unit and a perforator, to the input of which digital data are supplied from an analog-to-digital converter whose input is connected to the output of a commutator of analog input signals 2 A common drawback of the known devices is that there is no speed due to the fact that the units of the devices operate sequentially, without combining the operations in time. The purpose of the invention is to increase the speed of the device. The goal is achieved by the fact that the device for recording analog signals containing the first switch, analog-digital converter, second switch, executive unit, input and output of which are connected respectively to the first output and first input of the second switch, the second and third inputs of which are connected with the first and second outputs of the analog-digital converter, the first input of which is connected to the output of the first switch, whose information inputs are the inputs of the device, the OR element is entered, the first input of which is the control input of the device 391

device, the second is connected to the second output of the second switch, and the output is the second input of the analog-digital converter, the second output of which is connected to the control input of the first Switch.

FIG. 1 shows a block diagram of the proposed device; in fig. 2 diagram of analog-to-digital converter; in fig. 3 is a diagram of the second switch.

A device for tracing analog signals (Fig. 1); contains the first switch 1, analog-to-digital converter 2, second switch 3, executive unit C, element OR 5, control input 6, information inputs 7 An analog-digital converter (Fig. 2) contains the measuring limit selection unit 8, the sign determining unit 9 ,, block 10 converting the analog.

The second switch (Fig. 3) contains the trigger 11, the key 12, the counter 13, the It block of the switching keys, the block 15 of the driver amplifiers.

The device works as follows.

In the initial state, the first switch 1 connects the first information input 7, to which the first of the measured signals is fed, to the input of the analog-digital converter 2,

The measuring limits selection unit 8 and the sign determining unit 9 provide the signal and sign module modules to the information inputs of the analog-to-digit conversion unit 10.

When a pulse is received through the OR 5 element at the control input of the analog-digital converter 2, the latter is started up and at the end of the conversion process, its outputs are set in a parallel binary-ten code: the sign of the signal, the mantissa and the characteristic of the measurement result.

A pulse at the end of the measurement from the output of the analog-to-digital converter 2 is fed to the control input of the first switch 1 and provides the connection of the next input channel. At the same time, it is fed to the control input of the second switch 3 and sets the trigger 11 to the one state. The output signal from trigger 11 opens the key 12 and sync4

pulses from the output of the Executive unit k through the key 12 is fed to the input of the counter 13 and the block 15 of the amplifiers-drivers. Block 14 commuting

the keys are controlled by a parallel binary code from the counter 13 and provide a sequential output to the executive unit through the block 15 of the amplifiers-sign shapers, digits

mantissa, characteristics and splitter.

Simultaneous start of the first switch 1 and the second switch 3 provides a combination in time

arrival of input signals with registration in the execution unit k of measurement results.

After registration (perforation) of the characteristics of the next sync pulse through the counter 13 enters through the element OR 5 to the control input of the analog-digital converter 2 and starts it, which provides simultaneously with the registration in the executive unit of the information separator to convert the analog signal of the next channel into digital form.

After registration information from all information inputs device

is reset. (

The economic effect is to increase the speed of the device for recording analog signals by combining the operation of recording the measurement results and the separator and preparing the recorded information.
