DC bias

When describing a periodic function in the time domain, the DC bias, DC component, DC offset, or DC coefficient is the mean value of the waveform. If the mean amplitude is zero, there is no DC offset. A waveform without a DC component is known as a DC-balanced or DC-free waveform, also known as AC waveform.
