Description

(54) DIGITAL INDEX OF EXTREMUMS When there is no DC signal at the input of the chapters in the chapters ch to 2), the reversible counter 3 is in the initial state, at which at the output of the former 4, the equalizing eenpsoKetiBe U is output. organ 1 goes to a yellow one, and as a result, the first one is overhearted, one is over the counter, one is over the counter, one is ready for the maximum number (niox), and from the checkbox for the fourth side is sent to both of the slave for the maximum, (niox) naira tim l ud, which returns a null body 1 into the null state. The time required 1 discrete signal for one discrete signal Uc is determined by the eMfetieM fbhoSH andShutSya and zero-organ I through a positive feedback circuit (reversible counter, formI5 Equivalent voltage generator) to its balanced input. When the DC signal changes by d i, the second zero-orgina 1 is triggered and balanced, and so on throughout all the time while the signal UG rises upward until the time i, when the signal Uc reaches its maximum value. Starting with this task, at y {"1" of the signal of the signal Ts on the signal A, the null organ 2 is triggered, as a result of which it changes to a single state, which leads to a change in the state of the trigger 5. The appearance of the unit at the second input of the reversible counter 1flc leads to a decrease in the output voltage of the imaging unit 4 by the value of Discrete Data Samples, as a result of which the zero organ 2 after a time interval equal to the delay of the front of a single impulse during the passage of counter 3 and the imaging unit 4, returns to the zero state. The balancing process in the null-organ channel 2 continues until time tij, then the process repeats. Thus, during the passage of extrema, the state of the trigger under the influence of pulses from the exit of the null organs at times i and, which mark the moment of passage of the extrema, changes. Depending on the state from which the trigger goes to the new, either the passage of the maximum or the passage of the minimum is detected, which can be determined, for example, by differentiating the output trigger pulses, as shown in the UC-t diagram). FIG. 2, with STOM, the voltage symbol index means the romer of the block, to which it relates, invented digital invention of extrema containing the main null organ and the balancing voltage former, the input of which is connected to the output of the reversible counter, and the output is to the control input of the null organ, I distinguish it with that. That, in order to eliminate the possibility of the occurrence of false extremum signals, a trigger and an additional null organ are introduced into it, the signal and control inputs of which are connected to the corresponding inputs of the main zero-gate and the outputs of both null-organrv are connected to the corresponding trigger and reverse inputs counting Sources of information taken into account in the examination 1.
