Quizplus · Accepted Answer

If digital signaling elements all have the same algebraic sign, either positive or negative, then the signal is unipolar. Polar signaling refers to a system where the signal can have both positive and negative values. Baseband refers to a signal that has not been modulated, while differential signaling refers to a system that transmits data as differences between two signals.
