Abstract

The invention relates to modulation methods and systems and can be used for transmitting and receiving information signals. Said invention makes it possible to directly converting a digital signal or an information unit from known samples or prototypes by accurately forming an analog signal. The inventive method consists in determining the conformity of the analog signal sample having a specified period to the bits of a parallel digital code, to the positions of a sequential digital code or to an intelligible information unit, wherein each analog signal sample is selected according to the spectral characteristic thereof and, afterwards a sequential graft operation of the analog signals corresponding to the message information significance is carried out.

REMAINING EXISTING ELIMINATIONS The electronic system contains modulators and demodulators. 10 Modules (Fig. 1) includes: - Reg. 1 of the storage of the input; - synthesis of 2 samples of the signal; - Devices of 3 records of samples; - a digital-to-analog converter (CPU) 4. 5 Demodulator (Fig. 2) contains: - an analog-to-digital converter (CPU) 5; - memorizing device 6 for storing a commercially available code; - device 7 sync; 0 - device 8 Takes decisions, saves you a lot of money, which implements the functions of calculating functions (or other associative functions). Synchronization may occur internally of 5 generators (not shown on the drawer) due to loss of use.

Variable for modulation of the parameter can be called 5 informative parameter, for the most part in it changes the recorded information. Optionally, or an alternative parameter of the transmitter is in the form of an interface that defines the name of the modulation, which interferes with the signal transmission.

10 Signals are prevented by changing the currents or other parameters of the physical carrier by law, by sharing the signs that are suitable for transmission or storage. This process of changing the media settings, as it is, simply refers to modulation.

15 Amplitude, frequency, phase modulation is known, as well as pulse different types of modulation, single and multiple modulation, delta modulation, and delta modulation. Pay attention to the fact that the delta is a presentation

In this system, instead of the regular emissions values, only the difference sign is transferred between the current selected value and its assigned value. Аче In general, the quantified value is assumed to be the quantized value.

Due to this, the meaning of the message in every part of the system is supplied with a single binary, which reduces the amount of message being transmitted. 6 Pρi eτοm sledueτ ποdcheρκnuτ, chτο sοvρemenny uροven τeχniκi ποzvοlyaeτ dοsτaτοchnο τοchnο sinτeziροvaτ signals neποsρedsτvennο, chτο daeτ vοzmοzhnοsτ isποlzοvaτ for mοdulyatsii sοvοκuπnοsτ προτοτiποv dοsτaτοchnο slοzhnοy φορmy. 5 The proposed modulation method is implemented by the following method.
