Bias has numerous meanings. It literally means diagonal or slant.
Electronics
Bias is a DC voltage level added to an AC signal which is to be amplified. This is done to put the AC signal within the amplifying transistor's linear operating area.
Bias is also a name for a high-frequency sine wave that is added to an audio signal as part of the process of magnetic tape recording; it has the effect of eliminating distortion that would otherwise be caused by magnetic hysteresis.
Social Context
- Bias is also the predisposition toward one belief before another.
