Therefore, the signal of the third answer of prohibition 879622 will work the keys of block 13 and the elements And block corresponding to the question numbers will work 14. Through the OR element 16 and the key 18, the output signal acts on the cell of the inflation 23 Unsatisfactory 5. Similarly, a diagram is constructed for the case with four correct answers out of five, where block 10, 'OR element 17 and key 19 are used. In this case, five necessary and sufficient ¹⁰ combinations are possible - 1234, 1235, 1345, 1245, 2345, which are implemented in the device diagram control can be carried out variously. The output signal from this circuit includes an indication cell 24 “Good and ¹⁵ simultaneously prohibits the output of the signal from the OR element 16.

При пяти правильных ответах сигналы с выходов блока 6 подаются одновременно на элемент 21 ( в данном случае пятивхо- ²⁰довый), и в. соответствии с алгоритмами выходной сигнал воздействует на ячейку индикации 25 регистратора 26 Отлично’' и параллельно запрещает работу схемы Хорошо с помощью ключа 19.With five correct answers, the signals from the outputs of block 6 are fed simultaneously to element 21 (in this case, five-input ²⁰ ), and c. according to the algorithms, the output signal acts on the display cell 25 of the recorder 26 Excellent '' and in parallel prohibits the operation of the circuit Good with key 19.
