Description

one

The scheme relates to devices of technical cybernetics. And it can be used as a pointer to the highest or lowest voltage of a given set in devices of extreme control, reading graphs, choosing the direction of the pp optimization and recognition, and also perceptrons.

From (Bestna minimax circuit containing transistors, the bases; which are combined, and the collectors are connected via resistors through a power source. Such a circuit requires a lot of equipment to realize, besides, its speed is limited there, and it uses representation of input signals.

The proposed scheme differs from that in that, for the sake of simplification, the bases of the transistors are connected via a resistor to the source of direct bias and through the dc to the source of trigger signals, and the emitters of the transistors are connected to and from the source.

The drawing shows the proposed scheme. Minimax circuit for isolating the highest voltage across the aggregate of voltages, ..-, Fl1 and transferring them to the corresponding outputs in (as voltages

contains n transistors 1,2, ..., 3, the bases of which are connected together and through a common resistor 4 connected to the source of direct bias t / cu. depending on the use of normal or inverse switching of the transistors, the emitters ((collectors) are connected to the source of comparable voltages ff f2.., fl, and to the collectors (emitters) that are outputs, through the load resistances 5, 6, .. ., 7 connects the power source and the voltage of the same sign as the offset. The basic transistor circuits through the semiconductor | VODs-11 diode 8 are connected to the signal source XB, which brings the circuit into operation. In the off state, the X signal "More expected; MalJ": Ilm There are single-valued input voltages, and in the included one there are less than the minimum values expected by it.

After switching on the circuit, the largest of the input voltages ff phg, ..., fp increases the emitter. (Collector for inverse “switch”) current of the corresponding granulator, and since the resistances 5, 6, ..., 7 are greater than or equal to Saprotic displacement, this transistor transistor is saturated. An excess of current is absorbed into the ipan of the base circuit, causing an increase in the voltage across the resistor 4. As a result, the trajectory with the detector on the emitters ("hollers") smaller than the one received in the base pin, will end /with . So, if in the saturation mode (actually in inverse switching) the drop on the transistor is small, then at the output of the open transistor there appears a voltage almost equal to the voltage at its input. There is no voltage on the outputs of the other transistors, as they are closed.

If at the inputs of two or more and more voltage sensors are the same or close to each other, these transistors are simultaneously open. By adjusting the magnitude of the bias voltage, it is possible to set the maximum permissible deviations of the maximum voltages from each other, i.e., to change the resolution of the circuit.
