The term Phase is associated with which property of a cycle?

• A. Fraction of time it takes to complete a full cycle.
• B. Amplitude of the modulated signal.
• C. The impedance of the antenna feed.
• D. The regulatory restrictions on frequencies.

Answer: (A)

Phase tells you where you are in a repeating cycle; it describes how far through the period you’ve advanced, essentially the fraction of the cycle that has elapsed. If a cycle lasts T seconds, the phase corresponds to the portion t/T (or an angle 0 to 360 degrees) of the cycle completed at time t. That’s why phase is tied to the fraction of time it takes to complete a full cycle. It’s not about how tall the signal gets (amplitude), nor about how the circuit resists current (impedance), nor about rules for frequency use (regulatory restrictions).
