Definitions

  • the invention concerns a method of signal transmission and can be used to transmit electric signals in a sound channel.
  • Deficiencies of this method are low quality and absence of authenticity in the electric signal transmission in a sound channel.
  • the real sound signals of periodic nature having the frequency more than OHz have also the considerable asymmetry regarding to the axe of co-ordinates (Fig.3), and these signals correspond to signals received during performance of quick violin's passage.
  • the aim of the invention is radical upgrading the quality and authenticity of the electric signal transmission through a sound channel.
  • any extending the bandwidth of a sound channel in the infrasonic field (that is lower than the standard value of 20Hz) always upgrades the quality and authenticity of the sound signal transmission and so that allows to obtain the aim of the invention and receive a positive technical result.
  • a ideal chance for upgrading the operating quality of a sound channel is the frequency range of electric signal transmission from OHz, that is from the dc (direct current), but realisation of this frequency range is connected with some difficulties to supply stabilisation of the operating conditions of electronic devices on the dc.
  • OHz direct current
  • the electric signal transmission is realised through electronic devices of a sound channel from OHz by way of supplying electronic devices of a sound channel by circuits having open-ended input
  • the signal transmission with the frequency more than OHz is realised by forming a signal of the dc negative feedback in electronic devices independent on the asymmetry of electric signals and that makes accordance of the proposed technical embodiment to the criterion "novelty”.
  • the accordance of the proposed technical embodiment to the criterion "positive effect” is made by so that in the method-prototype the electrical signal transmission through electronic devices of a sound channel from OHz is realised in addition by way of supplying electronic devices of a sound channel by circuits having open-ended input, and the signal transmission with the frequency more than OHz is realised by forming a signal of the dc negative feedback in electronic devices independent on the asymmetry in initial electric signals.
  • This totality of the distinguish features used in the proposed method allows to upgrade the quality and authenticity of the electric signal transmission through a sound channel and that allows to draw a conclusion about accordance of the proposed technical embodiment to the criterion "positive effect”.
  • Fig.6 is represented by the most preferred structural diagram of a device and with its help it is possible to realise the proposed method.
  • the proposed method consists of the amplifier 1 with the negative feedback formed by the registers Rl and R2 having inverting and non-inverting inputs and also asymmetric output and the former 2 having the amplifier-limiter 3 and the integrator 4.
  • Electric signals are transmitted from input to output through the amplifier 1 by circuits having open-ended input, and the electric signal transmission of periodic nature with the frequency more than OHz is realised by forming a signal of the dc negative feedback in the amplifier 1 with the help of the former 2 by way of amplifying and limiting an output signal of the amplifier 1 on the amplitude by the amplifier 3 and by following transformation of a signal differing in the amplitude by duration into a signal differing in the amplitude with the help of the integrator 4. Formed by this way a signal of the dc negative feedback independent on the asymmetry of input signals of the amplifier 1 is transmitted from input of the integrator 4 of the former 2 to non-inverting input of the amplifier 1.

Abstract

L'invention concerne une technique de transmission de signaux et peut s'utiliser dans la transmission de signaux électriques dans un canal son. L'invention vise une amélioration radicale de la qualité et de l'authenticité de la transmission de signaux électriques dans un canal son. Le procédé permet la transmission sans distorsions et authentique de signaux électriques, au moyen de dispositifs électroniques, dans un canal son en utilisant des circuits ayant une entrée extensible; on effectue la transmission des signaux avec une fréquence supérieure à 0 Hz en formant un signal de rétroaction négative du c.c. dans des dispositifs électroniques, et ce indépendamment de l'asymétrie des signaux électriques.
