So I am getting into engineering and was curious what it means when a sine wave isn't even in a sense, at 0, from my understanding, the waveform has peak to peak amplitude of 4, while having a positive peak of 3 and negative peak of 1, does it mean anything in specific when it isn't even at a positive peak of 2 and negative peak of 2?

enter image description here


It means that there is a positive offset of one. So your signal is

$$ x(t) = 1 + 2 \cdot \sin(\omega t)$$


  • 1 is the offset
  • 2 is the amplitude of your signal (not 4).
  • $\begingroup$ Ahh that makes sense, thanks for the clarification $\endgroup$
