Question:
Tell which binary data format(s) shown in Figure 5.2 satisfy the following properties, assuming random (fair coin toss) data:
Figure 5.2
(a)?Zero DC level;(b)?A zero crossing for each data bit;(c) Binary 0 data bits represented by 0 voltage level for transmission and the waveform has nonzero DC level;(d) Binary 0 data bits represented by 0 voltage level for transmission and the waveform has zero DC level;
(e) The spectrum is zero at frequency zero (f = 0 Hz);
(f) The spectrum has a discrete spectral line at frequency zero (f = 0 Hz).
