Master molodcov_alex, а пилот-тон это тоже, что и leader tone?

"In order to ease the search for the block start, it is necessary to have on the beginning of each one a leader tone (808 Hz) that lasts for 3 or 5 seconds. It is followed by a short impulse (about 2500 Hz) called the synchro impulse, that specifies the start of the data block."



"когда идут данные - синим и желтым."
Типа 0-синий, 1 - желтый?
