The problem of reducing the low-frequency drift, "flicker" and blasting noise, generated in the measuring tract in the process of forming a digital equivalent for a measured value has been considered. Methods are proposed to further reduce the noise composition in the results obtained. The minimization of noise components of type 1/f, 1/f2 and irregular blast noise in the output digital...
This report examines a system for electronic measurement and calculation of the coordinates of an object on a target and subsequent reporting of a certain result on the position of the object. It is a method of locating objects using sound receivers — TDOA (Time Difference of Arrival), a part of multilateration (MLAT) method used to locate mobile phones, civil aviation aircraft, locating military...
This article, discusses the problem with the influence of offset voltages and their drives generated in the measuring system in the process of forming a digital equivalent to a pre-formed value. A method and a schematic solution are proposed to reduce the total offset voltages in a measuring line, based on the mixed signal technology. Its limitations have been defined in relation to transformation...
This report is dedicated to a new type of system used for testing electronic modules and designed specifically for the needs of the petroleum industry. After testing the electronic modules, the system makes a decision - suitable - unsuitable. Different communication modules communicate between the fuel dispensers and the POS (point of sale) system. The main goal is to raise the efficiency of the process...
