Изобретение относитс к магнитной записи, а именно к устройствам дл магнитной записи и воспроизведени речевого сигнала.The invention relates to magnetic recording, in particular, to devices for magnetic recording and reproduction of a speech signal.
Известное устройство аналогичного назначени , содержащее сопр гаемый с магнитной лентой блок универсальных магнитных головок , св занный с выходами преобразовател аналоговых сигналов в код. и с входами преобразовател кода в аналоговые сигналы, микрофон и громкоговоритель, не позвол ет получить высокую плотность записи без увеличени искажений воспроизведенного речевого сигнала.A known device of a similar purpose, comprising a magnetic tape adapter-compatible unit of universal magnetic heads associated with the outputs of the converter of analog signals into a code. and with the inputs of a code converter to analog signals, a microphone and a loudspeaker, it is not possible to obtain a high recording density without increasing the distortion of the reproduced speech signal.
Цель изобретени - увеличение плотности записи.The purpose of the invention is to increase the recording density.
Дл этого в предлагаемое устройство введены анализатор спектра речевого сигнала, включенный между микрофоном и преобразователем аналоговых сигналов в код, и синтезатор речевого сигнала, включенный между преобразователем кода в аналоговые сигналы и громкоговорителем.To do this, a speech spectrum analyzer, included between the microphone and the analog signal converter, is entered into the proposed device, and a speech signal synthesizer, connected between the code converter into the analog signals and the loudspeaker.
На чертеже изображен один из возможных вариантов предлагаемого устройства.The drawing shows one of the possible variants of the proposed device.
Микрофон 1 соединен с анализатором 2 спектра речевого сигнала, выходы которого св заны с входами преобразовател 3 аналоговых сигналов в код. Выходы преобразовател аналоговых сигналов в код подключены к блоку 4 универсальных магнитных головок.Microphone 1 is connected to speech spectrum analyzer 2, the outputs of which are connected to the transducer inputs of 3 analog signals to code. The outputs of the converter of analog signals into a code are connected to a block of 4 universal magnetic heads.
сопр гаемому с магнитной лентой 5, котора перемещаетс посредством лентопрот жного механизма 6. Блок 4 св зан также с входами преобразовател 7, выходы которого подключены к входам синтезатора 8 речевого сигнала . Выход синтезатора соединен с громкоговорителем 9.magnetic tape 5, which is moved by a tape drive mechanism 6. Block 4 is also connected to the inputs of the converter 7, the outputs of which are connected to the inputs of the speech signal synthesizer 8. The output of the synthesizer is connected to the loudspeaker 9.
Речевой сигнал, поступающий с микрофона 1, нреобразуетс анализатором 2 в сигналы-The speech signal from microphone 1 is converted by analyzer 2 into
параметры. , Последние преобразователем 3 преобразуютс в код, записываемый на магнитную ленту 5. Воспроизведенный с магнитной ленты код преобразуетс сначала в аналоговые сигналы, которые затем синтезаторомoptions. The latter by converter 3 are converted into code recorded on magnetic tape 5. The code reproduced from the magnetic tape is first converted into analog signals, which are then synthesized
8 преобразуютс в речевой сигнал, поступающий на громкоговоритель 9.8 is converted into a speech signal input to the speaker 9.
Предмет изобретени Subject invention
Устройство дл магнитной записи и воспроизведени речевого сигнала, содержащее сопр гаемый с магнитной лентой блок универсальных магнитных головок, св занный с выходами преобразовател аналоговых сигналовA device for magnetic recording and reproduction of a speech signal containing a magnetic tape mating unit of universal magnetic heads associated with the outputs of an analog signal converter
в код и с входами преобразовател кода в аналоговые сигналы, микрофон и громкоговоритель , отличающеес тем, что, с целью увеличени плотности записи, в него введены анализатор снектра речевого сигнала, включенный между микрофоном и преобразователем аналоговых сигналов в код, и синтезатор речевого сигнала, включенный между преобразователем кода в аналоговые сигналы и громкоговорителем .Into the code and with the inputs of the converter of the code into analog signals, a microphone and a loudspeaker, characterized in that, in order to increase the recording density, a speech spectrum analyzer connected between the microphone and the converter of analog signals into the code, and a speech synthesizer included between the code converter to analog signals and the loudspeaker.
