The invention relates to radio and electric communication, data transmitting and, in particular, can be used for converting binary code to transceiver devices, recording processing and storing of information.The problem, solved by the invention, comprises creation more simple, compared to a prototype, a method of converting a binary code to an analog signal without substantial frequency rise using a sufficiently simple apparatus both at transmitting/receiving sides.The inventive task is characterized in that the prior of the use of binary code as a support signal to convert an analog code either one or a plurality of harmonic oscillation periods with zero voltage value at edges, modulation is carried out passing at the exit a support signal at the exit the binary code during passing a binary code and closing during the zero passing, wherein the support frequency signal is set being higher or equal to binary code frequency.There are other differences from the prototype.The inventive method permits to design communication systems keeping the prior art merits of analog and digital conversion, to update the existing analog paths with a considerable increase of channel number and transfer them to a modern digital base. |
