Description

же обмотки возбзждени  10 и 11. На обмотки возбуждени  напр жение поступает с трансформатора 12, выполненного с переменным резистором 13, снимаетс  же напр лсение с помош,ью обмоток 14 и 15, составл ющих в совокупности выходной трансформатор. При этом обмотка 14  вл етс  первичной, а 15 - вторичной.The same excitation winding 10 and 11. The excitation winding is supplied from a transformer 12 made with a variable resistor 13, the same voltage is removed by means of windings 14 and 15, which together form the output transformer. In this case, winding 14 is primary, and 15 is secondary.

При отсутствии на магнитном носителе записанной ранее информации, т. е. при отсутствии с него магнитного потока токи в ветв х и част х магнитопровода, возбуждение которых происходит при участке обмоток 10 и И, будут отсутствовать в первичной обмотке 14. Это обусловлено симметричностью ветвей и участков. При наличии на носителе информации , записанной ранее, подмагничивание в одной части магнитопроБода увеличиваетс  за счет суммировани  потоков от обмоток смещени  и возбуждеии , а в другой уменьшаетс . Тогда на обмотке 14 по вл етс  разность токов от воздействи  указанных потоков, а на обмотке 15 - выходное напр жение.In the absence of previously recorded information on a magnetic medium, i.e., in the absence of a magnetic flux from it, currents in the branches and parts of the magnetic circuit, which are excited at the winding section 10 and I, will be absent in the primary winding 14. This is due to the symmetry of the branches and plots. When there is information on a recording medium recorded earlier, the magnetization in one part of the magnetic conductor increases due to the summation of the currents from the bias windings and excitation, and in the other decreases. Then, on the winding 14, the difference of the currents from the effect of the indicated currents appears, and on the winding 15 - the output voltage.

Таким образом, ММГ может работать как модул тор, что  вл етс  важным дл  устройств , где необходимо одновременно с воспроизведением ранее записанной информации осуществл ть и модул цию потока.Thus, MMG can work as a modulator, which is important for devices where it is necessary simultaneously with the reproduction of previously recorded information to implement the modulation of the stream.
