# What meaning does the following sine wave have when it comes to amplitude?

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?

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