The electronic firmware synchronization was its method where even the series of bytes is amplified even before the transmission process into to the sound waves and, thus, and in conceptual "1s" and "0s" represented by large font, wavelengths, or switching frequency.
QAM utilizes both magnitudes of the transporter and adjustments in the phase shift.
Rational data is represented by cartesian coordinates for both the carries waves of the same wavelengths and represents the result in total.
