Description

The invention relates to a measuring technique and can be used to register the shape of single pulse signals, in particular during registration, forks long-lasting signals. A digital recorder of the shape of single pulse signals is known, containing serially connected signal sensors, analog-to-digital converters, code fixing unit and fast response memory node, as well as a generator, the output of which is connected to the control (synchronizing) inputs of the analog-to-digital converter and memory la -r 1. However ET1Y registers the storage information stored in the registration .protsesse, requires a considerable amount of memory okazyvayuschiy-: a very large length in the registration-negative signals. The purpose of the invention is to reduce the amount of stored information when registering pulse signals. The goal is achieved by the fact that an adaptive recorder containing a generator, an analog-to-digital converter whose outputs are connected to a code-fixing unit, and an input is connected to a signal sensor, while the outputs of the code-fixing unit are connected to the first inputs of the memory block, a pulse shaper is entered, the switching node, the counter and the logic unit, the inputs of which are connected to the outputs of the analog-digital converter, and the output connected to the first input of the switching node, the second inputs of which It is connected to the generator through the pulse shaper, with the first output connected to the second input of the code fixing unit, through a counter with the second inputs of the storage unit and the third input of the last, and the second outputs connected to the fourth inputs of the storage unit. The drawing shows a structural electrical circuit of an adaptive recorder. The recorder circuit contains a signal sensor 1, an analog-digital converter 2, a code fixing unit 3, a logic unit 4, a switching node 5, a pulse trainer 6, an oscillator 7, a memorization unit 8, a counter 9.

The proposed device works as follows.

When a recorded signal from the output of sensor 1 arrives at the input of analog-digital converter 2, code combinations corresponding to the instantaneous values of the incoming signal appear at its outputs. From the output of the analog-to-digital converter 2, the code combinations are fed to the first (informational) inputs of the fixing unit 3 and the inputs of the logic unit 4, which at the times of changing the code combinations produces output pulses. These pulses arrive at the first input of the switching unit 5, to the second inputs of which from the outputs of the sequence generator 6 are fed to sequences of pulses having different follow-up periods.

Let us assume that a larger number corresponds to a sequence of pulses that have a longer period (i.e., the shortest period has the first sequence, the largest - k-a).

In the switching node 5, the time intervals between the pulses arriving at its first input are compared simultaneously with all the periods of the succession of impulses arriving at its second inputs. The switching device 5 determines the highest number of the pulse sequence, the period of which is shorter than the time interval between the pulses received at its first input. After that, at the first output of the switching node 5, there appear m pulses from the pulse sequence defined above, and at its second outputs, the code combination corresponding to the number of the determined sequence. The pulses from the first output of the switching unit dego 5 are sent to the second (control) input of the fixing unit of code 3, which ensures fixing (remembering) the code combination received from the output of the analog-digital converter 2 to the input of the counter 9, where they accumulate, the third (control) input of the storage unit 8, which ensures the recording of code combinations received at the first, second and fourth of its inputs.

Thus, in the storage unit 8, the instantaneous values (in digital form) of the signal received from the output of the sensor 1 are recorded, as well as the number of the pulse when the corresponding instantaneous value was taken, and the number of the period following these pulses.

After the passage of the last t-th pulse switch, node 5 again generates m pulses (possibly of a different following period, it depends on the last time interval between the pulses received at the first input of switching node 5 by the end of the m-th pulse of the previous series) and (as described above) writing data to the storage unit 8.
