  • Transcript

    • 1. Simple Waveform Polarity and Interaction
    • 2. a simple sine wave the signal is bi-polar (it oscillates between positive and negative values)
    • 3. Polarity • the property of being polar (having positive and negative values) • the relationship between the positive and negative portions of two waves
    • 4. same polarity • these two signals have the same polarity • when one is positive, the other is also positive • when one is negative, the other is also negative
    • 5. different signals - same polarity • these two signals are different, but they have the same polarity • when one is positive, the other is also positive • when one is negative, the other is also negative
    • 6. opposite polarity • these two signals have opposite polarity • when one is positive, the other is negative • when one is negative, the other is positive
    • 7. What happens when two identical signals are combined (added together)?
    • 8. same polarity addition • these two signals have the same polarity • when they are combined (added together)...
    • 9. the amplitude doubles =
    • 10. What happens when two signals with opposite polarity are combined (added together)?
    • 11. opposite polarity addition • these two signals have opposite polarity • when they are combined (added together)...
    • 12. the waveforms cancel each other out =
