- Digital radio transmits bits by creating discrete states, usually discrete amplitudes and phases of a carrier. The process of creating these discrete states from a digital bitstream is called digital modulation. A state is established at a particular time called a clock tick.phys.libretexts.org/Courses/Kettering_University/Electricity_and_Magnetism_wit…
