Description

(54) DIFFERENTIATING SMOOTHING The invention relates to computing and can be used in the automation of information processing systems. A differentiating-smoothing device is known that contains a Kotz voltage converter, a memory (memory register), an adder (reversible counter), AND logic and a control unit, in which two time-separated measurements are used to determine the derivative ( The disadvantage of such a device is SIBL51 - poor filtering of low-frequency interference, the period of change of which exceeds the period of signal acquisition. The closest in technical essence to the proposed It differentiates and smoothes the device, which consists of transforming a voltage of 4s, shifting registers, a code-voltage converter, investing and summing amplifiers. The output value of the output is represented as voltage 2. In the diagram of this device, the intermediate conversion into a figure (using a voltage-code converter) is used to increase the accuracy of the frequency of fermentation (multiple frequency signals, and the derivatives of derivatives are also based on the determination of the difference between the two rhenium. Code-to-voltage converter allows this to be easily implemented in analog form, by using inverting and summing amplifiers, but at the same time, the representation of analogue-derived products narrows the scope of this device. The noise resistance of this device is by averaging over the conversion interval. , i.e., by selecting the noise-resistant structure of the converter, iMt one. However, for slowly varying quantities with additive low-frequency interference, averaging over the conversion interval

The device contains an adder 1, a converter 2 voltage-frequency key Sv synchronization unit 4, a counter 5g keys 6, a count of 7 kg, an 8, a reg 1 page 9 and a memory that converts 11 a code,

The device works as a backup.

When applying to the input of the HEinpsf device, the frequency sigal corresponding to this voltage from the output of the transform gel 2 has a frequency of 3 to the counters 5 and 7, on which a number is proportional to the value of

The control impulse 7 is converted into memory register 9. The next pulse of block 4 overwrites the contents of counter 5 into memory register 1 in direct code and in counter 7 in additional code, after which counter 5 is zeroed, in the second

and following the cycles of conversion. At the output of the summatr I, a sipnal is formed with the feedback voltage feedback voltage. exi oc l and t, a, DruP1Mi and in words, there is a recurring record of the input information, while the earlier values of the input information are taken with a lower weight, Tee. the input signal is smoothed on the interval, exceeding the duration of one cycle. The smoothed values are and the values of increments coming from counter 7 to the register The parameters of the exponential smoothing are determined by the value of the coefficient K

The technical and economic effect of the use of the invention is determined by the improved interference with the device,
