(54) DEVICE FOR DETERMINING THE EXTREMUMA OF A RANDOM PROCESS whose inputs are connected by: outputs nej. first and second elements And, and outputs with the first and second outputs of the device, respectively. The block diagram of the device is shown in black. The device contains a bit 1: bits from triggers 2, zero 3 to a single 4 outputs which are connected respectively through the elements NOT 5 and elements AND 6 to the inputs of the elements OR 7, the outputs of which through the pulse shaper 8 are connected to the second inputs of the elements 6. The input the first generation driver 8 is connected to a single output 4 of the first three mode 2, the output 9 of the driver is connected to the input of the HE 10 element, the outputs 11 and 12 of the trigger 13 are connected to the outputs of the device. The outputs of the And 14 elements are connected to the inputs of the flip-flops 2 and 13, and the inputs to the inputs of the device and the outputs of the former 8 and the element NOT 10, respectively. The device works as follows. In block 1, the least significant bit is on the left. All circuit elements respond only to positive pulses. At the start of operation, all the triggers are in the zero state, and at the outputs of the HE 5 elements and the HE 10 element there is a high potential. The presence of a high potential at one of the inputs of the And 6 elements ensures the free passage of positive pulses along the circuit from left to right, which can be formed at the outputs of the 4 flip-flops 2, when going from one state to zero. When triggers 2 transition from zero to one at the outputs 3, positive pulses are generated, which lead to the disappearance of the positive potential at the outputs of the elements NOT 5. At the same time, the passage of pulses through the corresponding elements 6 is excluded. When entering increasing numbers into block 1, the trigger state 13 does not change. In this case, two cases are possible. In the first case, increasing numbers are formed by increasing the number of units. Consequently, there are transitions of the flip-flops 2 only from the zero state to one, that is, at the outputs 4, signals that are transmitted along the circuit are not formed. In the second case, an increase in the number occurs due to the movement of units and into the most significant bit, and zero to the younger. In this case, the low-order trigger goes to the zero state, and a positive impulse occurs at its output 4, which moves along the circuit to the 13-trigger. However, the transition of the trigger bit & bit to one leads to the removal of the positive signal from the corresponding element And, which excludes the passage of a positive impulse formed by the low-order trigger to trigger 13. From the moment of passing the positive on the extremum, decreasing numbers begin to be entered into block 1. Moreover, the transition of any trigger from the single state to the zero state leads to the transfer of the trigger 13 to the single state. As long as descending numbers are entered into the register, positive impulses arrive at the single input of trigger 13. From the moment of passing through the negative extremum, increasing numbers are entered in block 1. In this case, the positive pulses do not pass through the circuit, which leads to the appearance of a positive potential at the output of the element NE and the transfer of the trigger 13 to the zero state.
