Q

Determine the phase relationship between the two signals shown in Figure 3B3.

🔍 Key Concepts

• Phase difference between two sinusoidal signals (in degrees) • How the horizontal shift between two waveforms relates to phase angle • Direction of shift and what it means to lead vs lag

💭 Think About

• Look at where each waveform crosses the zero line going positive: which one does this first, A or B? • Estimate what fraction of a full cycle (360°) the horizontal shift between A and B represents. • Decide whether the signal that reaches its peaks and zero crossings earlier is said to lead or lag the other.

✅ Before You Answer

• Identify clearly which signal is ahead in time at corresponding points (peaks, zero crossings) before choosing. • Confirm whether the time shift looks closer to a quarter of a cycle (90°) or half a cycle (180°). • Double-check the meaning of leading vs lagging so you don’t accidentally reverse the relationship.
