Definitions
- the invention is subject to methods and systems of communication and may be used to transmit signals. YOU ARE ALREADY Known for modulation for the transmission of information signals in the long wavelength, which is also turned on, which means that the signal is inhibited

- the electronic system contains modulators and demodulators.
- 10 Modules 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 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.
- SIGNIFICANT FOX (DR. 26) 5 Modulation is subject to a change in any parameter of the conversion (amplitudes, frequencies, etc.) or a slight change in signal to modulate it. Variable for modulation of the parameter can be called 5 informative parameter, for the most part in it changes the recorded information.
- 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.
- each sample of the analog signal is selected based on its specific 5 characteristics.
- SIGNIFICANT FOX (DR. 26) 8 to the CPU 5.
- the signal received from the channel in the form of digital counts from the CPU 5 is used for memorizing device 6 for the storage of the received data.
- the memorizing device 6 transfers the accounts to the synchronization device 7, 5 quick synchronization of the system. If you take a decision to read the device, 7 synchronization will give you the command to transmit the part of the implementation to the device 8 to take a decision.
