Description

23. Благодар  этому, сравнение происходит в моменты времени, расположенные точно посередине между синхронизирующими сигналами . В зависимости от соотношени  сигналов на входах схем И 6-10 и схем И 11 и 12, подключенных через резисторы 25 и 26 к второму входу 30 схемы сравнени  23, напр жение на этом входе может принимать значение, равное величине посто нной составл ющей на входе 29, либо больше или меньше этой величины (см. фиг. 2, з), и соответственно положение фронтов тока записи корректируетс  по времени (см. фиг. 2, и).23. Due to this, the comparison takes place at times exactly in the middle between the synchronization signals. Depending on the ratio of the signals at the inputs of the circuits AND 6-10 and the circuits AND 11 and 12, connected through resistors 25 and 26 to the second input 30 of the comparison circuit 23, the voltage at this input can be equal to the constant component 29, either more or less than this value (see Fig. 2, h), and accordingly the position of the edges of the recording current is corrected in time (see Fig. 2, i).
