Using only one Harmonic
To simplify the discussion. imagine that our computer creates just 6 bps. We make this unrealistic assumption just be able to show things graphically. Every second, 6 bits to are produced by computer. One second. we may have 111 111. another second the 001010, another second 10, and so on. We use an encoding method that uses positive value to represent 1 and a negative value to represent 0. Figure 3.18 shows signals.
