Description

The invention relates to a measuring technique and can be used to transfer measuring signals of a deterministic pulse sequence from a source of signals with high internal resistance to a capacitive load, for example a cable line.

The purpose of the invention is to increase the speed of the device.

Fig about 1 shows a functional diagram of the device; Fig. 2 shows stress plots showing his work.

A pulse-sequence signaling device contains a voltage source 1 with a high internal resistance, a capacitive load 2 connected in parallel between the first output. 3 voltage sources and capacitive load power amplifier 4 and passive switch 5, driver 6 sync pulses connected to the second output of the voltage source, trigger 7, the outputs of which are connected respectively to controlled inputs of the passive switch and power amplifier, zero-organ 8, element 9 delays and element 10, with the first inputs of the zero-body connected to the first input of the voltage source, the second input to the capacitive load, and the first output connected to the second input of the trigger, the first input of which is connected to the output A and 10, the first input of which is connected via a delay element 9, to the output of shaper 6 and the second input - to the second output of the zero-organ

The device works as follows.

The pulse sequence signal from voltage source 1 is fed to the inputs of power amplifier 4 (figure 2, plot 3), key 5 and null organ 8. Simultaneously from the second output of source 1, synchronization signals are sent to driver 6 (figure 2, plot 6 ), coinciding in time with the moments of the amplitude change of the pulse sequence signal.

At the time of arrival of the sync pulse trigger 7, in the case of a positive potential on the element 10 through the delay element 9 is set to the position in which the passive switch 5 is closed and the power amplifier transmits the change signal 3 pulse.

clear sequence from the input to the output, in this case, the capacitive load 2 (figure 2, plots 11 and 12). The transient time depends on the characteristics of the power amplifier and the magnitude of the capacitive load. Upon reaching relative equality at the inputs of the null organ 8, the last

10 generates a signal at the first output (plot 8), which triggers trigger 7 to the opposite state. In this case, the power amplifier 4 is turned off and at the same time the passive key 5, which transmits the exact value of the amplitude of the pulse sequence (FIG. 2, plots 13 and 14 in the signal generating zones 8), and at the second zero-output

20, a potential for the element I 10 is formed. In order for the device to work properly, the zone of sensitivity of the zero-organ to the equality of the input parameters is chosen to be somewhat wider in relation to the accuracy of signal transmission of the power amplifier. Fragments of signal transmission at these points are shown in plots 13 and 14, where E is the minimum voltage, with

35 the voltage at the inputs of the zero-organ, and therefore, at the input and output of the device are equal, the negative potential from the second output of the zero-organ does not pass the next signal from the output of the driver 6. In this case, the trigger 7 remains at the position at which the input and the output of the device is connected with the passive key 5, i.e. need to connect an amplifier

Thus, the device due to

adjusting the transient time depending on the difference in the levels of adjacent signals provides a reduction in the time required for. its transfer from one information level to another, and increasing its speed, which allows to condense the communication channel.
