The device autocalculation simplicity due to the use of three amplitude discrimination. However, the drawback is its large redundancy registruime information, as well as reports of amplitude over time in areas with fast growing front of the input voltage are separated from each other at distances smaller than required by the Nyquist theoremto guarantee the required accuracy of the recovery of the original signal.
The aim of the invention is the reduction in the volume of recorded data, preserving fidelity.
This objective is achieved in that the device for inputting information containing analog switch 2, the entrance of which is an information input device 1, and the output connected to the inputs of Comparators lower 3 and upper 4 levels, the second inputs of which across the circuit level shift 9, 10 connected to the generator output step voltage 8 summarizing and subtractive inputs of which are connected to the inputs of the OR element 13, the pulse generator 14, the output of which is connected to the first input element And 15, a second input connected to the direct output of the RS flip-flop 16, and the output connected to the counting input the counter 17, the bit outputs of which are connected with the first inputs of elements And the second group 18, the outputs of which are second outputs of the device 19, and the output of the delay element 23 is connected to the installation is the input of the counter 17, introduced four shaper 6, 7, 21 and 22, the one-shot 20 and the elements I the first group, the first inputs of which are connected to data outputs of the generator speed voltage 8, and outputs the first output device 12, and second input elements I connected to the output of the shaper 21 and to the input of the delay element 23, the output of which is connected also to the input S installation per unit RS-flip-flop 16, the input R set to "0" which is connected to the output of the imaging unit 22 and to the second inputs of elements And 18 of the second group, the outputs of which are the second output device 19, the output of the upper comparator 4 is connected via the driver 7 summarizes the generator input speed voltage 8, the subtractive input connected to the output of the imaging unit 6 connected to its input through an inverter 5 with the output of the comparator 3 lower level, while the output of the OR element 13 is connected to the input of one-shot 20, the output of which is connected to the inputs of the formers 21 and 22.
Figure 1 shows the functional diagram of the device for inputting information, figure 2 and figure 3 - timing diagram explaining his work.
Device for entering information works as follows.
In the initial state of the analog switch 2 is open, RS-trigger 16 and the counter 17 is reset to zero, the output of the generator speed voltage level of the voltage is of zero so on the second comparator input 3 zero potential and the second input of the comparator 4, the potential is determined by the number of directly biased diode in the circuit of the level shift 9.
Assume that the input voltage at the input 1 increases from zero. As soon as this voltage exceeds the potential level of the second input of the comparator 4, its output will appear high potential. After (chart figa) passing shaper 7, which represents the allocation of the leading edge (figure figb - U6), which appeared a short pulse will trigger the one-shot 20 through the element OR 13. Simultaneously, the pulse will arrive at the summing input of the generator speed voltage 8. The potential at the output of the generator 8 will rise one degree, so that the output circuits of the shift level 9 and 10 appears a potential difference U2-U1=ΔU the voltage U1will be applied to the second comparator input of the lower layer 3, and the voltage U2to the second input of comparator upper level 3, so that the input voltage will be within the level of quantization ΔU=U2-U1. With further increase of the input voltage it will reach U2, resulting in the output of the comparator upper level will have a high potential through the shaper 7 and helped it become the on the summation generator input step voltage 8, as a result the potential at the output will increase by one level, and so on. The process will continue up until will be an increase in the input voltage, so that the second inputs of the Comparators 3 and 4 will be observed potentials UiUi+1different is always on value ΔU=Ui+1-Ui(figa). Once the input voltage reaches a maximum and begins to decrease, at the intersection of the level comparator lower level 3 at its output appears low potential through the inverter 5 and the imaging unit 6 (representing the allocation of the trailing edge, U7 on figb) will go to the subtractive input of the generator speed voltage 8, so that the potential at the output will be lowered by one notch. The process will be repeated in the same sequence as the input voltage will decrease.
The chart figa shows a graph of the voltage at the generator output step voltage.
Upon receipt of the leading edge of the pulse from the output of the shaper 7 and item OR 13 to the input of one-shot 20, the latter is triggered and its output goes high potential (chart U20figure 2). The time spent in the relaxation period is determined by its parameters τρ=τn,the duration of the pulse at its output opredeliaetsia time during which he is not sensitive to the input pulse. At the end of the relaxation period at the output of one-shot 20, the voltage is returned to "0". At the output of the imaging unit 21, which represents the allocation of the trailing edge, you receive a positive pulse which is fed to the second inputs of the elements I the first group, and the potential for informational outputs of the generator speed voltage 8 proceed to the first output device 12, forming a binary amplitude. Simultaneously, a positive pulse from the output of the imaging unit 21 is supplied through the delay element 23 on the installation entrance 12 of the counter 17 and to the input of the S-set to "1" RS-flip-flop 16, which moves into its second stable state, with its direct output goes high potential, which opens the item And 15. The pulse generator 14 start to arrive at the counting input of counter 17, filling it. With the arrival of the next pulse from the output element OR 13 one-shot 20 is triggered, and its output goes high potential, through which the imaging unit 22, which is the allocation of the leading edge, translates RS-trigger input R to its original state. The element 15 is closed, stopping the flow of pulses to the counting input of counter 17. At the same time the pulse from the output of the imaging unit 22 falls on the second input elements A second group, and high potentials with a bit outputs of the counter 17 are on the output device 19, forming a binary code time.
The positive effect of the implementation of the proposed device for inputting information is illustrated by the diagram in figure 3.
The device implements two-way measurement values of reference amplitude and time.
The voltage is measured at the time of the return of the one-shot 20 in the initial state (trailing edge). In this time of open elements I the first group, and the voltage from the bit outputs of the reversible counter and generator speed voltage 8 output 12, thus forming the code of the amplitude. The pulses coming from the output of the comparator 4 (when the reverse process - comparator 3 through the forming unit 7 (6) and element ILI during the relaxation of the one-shot 20 at its input, will be absorbed without causing its actuation. For signals with a limited range of the relaxation time is equalwhere ΔFCthe upper cutoff frequency of the signal spectrum, which guarantees the highest accuracy recovery. On the gently sloping portions of the input signal crossing time of two adjacent levels Uiand Ui+1may significantly exceed τρ. In this case, start the control mechanism, in which C is ne front the one-shot 20 (scheme of selection of the trailing edge 21) tipped RS-trigger 16, which opens the element 15, and the pulse generator 14 is filled, the counter 17. This process continues until the next actuation of the comparator 4.
The leading edge was matched, the one-shot 20 (from the output of the shaper 22) will return the trigger 16 to its original state. Simultaneously, the content of the counter 17 through the elements 17 of the second group appears on the second output device 19, forming a binary code time. The time between two consecutive activations of the comparator will be the value of
where F2- frequency pulse generator 14,
n is the number of pulses accumulated in the counter 17 during the time between two activations of the Comparators.
Thus, the binary expression of the number n is recorded on the second output device 19.
