Description
етс на стирающую головку 3 и производит размагничивание носител . На размагниченный носитель записываетс ЧМ сигнал. Двига сь в зазоре блока воспроизвод щих голо вок 6, магнитный носитель наводит в общей обмотке 12 суммарную э. д. с. Необходимые весовые коэффициенты создаютс выбором ширины магнитных пакетов 9 пропорционально интервалам между ноль-пересечени ми временной функции записываемого сигнала. Э.Д.С., возникающа в общей обмотке, поступает на вход интегрирующего усилител 7. С выхода усилител 7 снимаетс ЧМ сигнал.on erasing head 3 and demagnetizes the carrier. A demagnetized medium is recorded on the FM signal. Moving in the gap of the reproducing head 6, the magnetic carrier induces a total e in the common winding 12. d. The necessary weights are created by selecting the width of the magnetic packets 9 in proportion to the intervals between the zero intersections of the time function of the recorded signal. An emf arising in the common winding is fed to the input of the integrating amplifier 7. From the output of amplifier 7, the FM signal is removed.
Предмет изобретени Subject invention
Устройство дл сжати частотно-модулированных сигналов, содержащее магнитные головки записи и воспроизведени , стирающую головку, соединенную с генератором стирани , интегрирующий усилитель, соединенный с головкой воспроизведени , и магнитный носитель , отличающеес тем, что, с целью повыщени экономичности, упрощени электрической схемы и уменьшени габаритов, магнитна головка воспроизведени выполнена в виде блока из С-образных провод щих и изолирующих пластин, сформированных в симметрично расположенные относительно середины блока, убывающие по толщине nponopj ционально ноль-пересечени м временной функции обрабатываемого сигнала пакеты,A device for compressing frequency-modulated signals, comprising magnetic recording and reproducing heads, an erasing head connected to an erase generator, an integrating amplifier connected to the playback head, and a magnetic carrier, characterized in that, in order to increase efficiency, simplify the circuitry and reduce dimensions, the magnetic reproduction head is made in the form of a block of C-shaped conductive and insulating plates, formed in symmetrically located relative to the middle block, decreasing in thickness nponopj rationally by zero-intersections of the time function of the signal being processed,
при этом магнитный носитель помещен в полости зазора указанных пластин, которые охвачены общей обмоткой.however, the magnetic carrier is placed in the cavity of the gap of these plates, which are covered by a common winding.
