Description

The device relates to information-measuring technology and can be used in telemetry, as well as in communication systems, telecontrol, etc. A receiving device is known that contains a linear part of a receiver, a frequency detector and an auto-tuning unit, frequencies that provide reception of useful signals in the background interference, a low-pass filter (LPF), a peak detector, an adjustable amplifier, two comparison circuits, a level lock and a frame pulse selector used to separate informational and personnel amplifiers, subcommutators, Suitable dispensers of about pulses widened motors or LPF employed to obtain the recovered analog signals of the amplitude-modulated pulses, and the inverter voltage code that provides coding of these pulses. Thus, the device provides representation of recovery signals in both analog and digital form. The disadvantage of this device is the lack of adaptive interrogation of signals on the transmitting part of the telemeasurement system, since the sequence of connection of the pulse extenders (or channels) is determined by the distributor 1. Free from this disadvantage, the receiving device 2 of the telemetric system, containing an intermediate memory block (BPP), whose input to the input of the device, one output is connected to the input of the digital-to-analog converter, in each information channel the registration unit, and the electron beam PLC tube, digital analog / address mapper. The output of the device is a CRT screen, the horizontal devi ated input is connected to the second output of the intermediate memory block via an address DAC, and the luminance brightness control input is directly to the third output of the intermediate memory block (intermittent amplifiers

are taken into account.). The input information, which is also on each of the two parts, namely, the address code and the reference code, goes to the intermediate memory block in it by outputs: the address code controls the status of the address DAC, and the reference code controls the reference DAC. , the output voltages of both DACs move the beam, CRT to the appropriate place on the screen, where. is highlighted, the Point Memorization point is due to the afterglow of the CRT screen. Each channel corresponds to one or another position on the horizontal axis (address), the value from; Counting is determined by vertical ness with respect to the zero line. At the time of transient processes in the PPP, PAP, the CRT beam is blocked by a signal from the PPP (control of the luminosity of the CRT), the disadvantage of the prototype device is small and e4x |) effective, since only zero extrapolation of telemetry signals can be used in it.

The purpose of the proposed NPU device is to expand the functionality, i.e., the possibility of concurrency to restore polynomials of degree higher than zero. The goal is achieved by inserting an address decoder, an analog memory block, a low-pass filter and a serially connected counter, memory register and decryption | RATOR on resistors, the output of which is 1; is connected to the control input of the low-pass filter, which is connected to the registration unit; the output of the intermediate memory unit is connected to each information processor via the address decoder: a channel with the control input of the analog memory unit , with a zero input of the counter and an input of the register of the memory register, the inputs of the information channel counters are connected to the clock bus, the output of the digital-to-analog converter in each information channel goes to the input of the analog memory block, the output which soitsinei with input low-pass filter,

Due to this, polynomials are used as the device functions in the device: more than Bfc.icoKHx
