SU369583A1 - DEVICE FOR ADDITIVE PARAMETRIC CENTERING OF RANDOM PROCESSES - Google Patents

Description

one

The invention refers to the field of specialized means of analog computing technology intended for the processing of random processes.

The known devices of the same izpacchepp contain a dispersion calculator, integrators and a subtraction unit.

The described device makes it possible to improve the accuracy of centering in the absence of an is a scheme of nonlinear elements.

This device differs from each other in that it contains a liTOpoii filter integrator and a second 1; block; the output of the primary filter of the integrator is connected via a scale to the input of the first subtracter, and through the second filter integrator. to the second input of my subtraction, P1, its block, which is connected to the first input of the second grabbing block, connected by a second input to the input of the first filter-integrator.

The openness of a tekpubgoi zapachapp of the nonstandard arithmetical expectation is formed through a parametric function, with the account of which the indicated gauge takes the form:

/ 7Zrv (/) 2Xi ((0, (1)

where X | (/) is the estimate of the current average at the output of the first filter integrator;

l and H) is a current average average output of the second filter integrator.

The block diagram of the device shown in the drawing.

The input signal is fed through the first fi.tp-integrator / and large-scale amplifier 2 to the summing input of the subtraction unit 3. The output spgnna filter / enters through BTOpoii (| 1n, 1ртр -11теггтор 4 to subtract the input of the black chip.: Nanrie P1ea Output b, -1ok 3 corresponds to open (1). At the second subtractive block J, subtracting of the snnal (1) from the additive mixture, i.e. from the input signal, takes place.
