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.
Statistics
Bias means flaws in the collection, analysis or interpretation of research data that lead to incorrect conclusions.
Social Context
- Bias is also the predisposition toward one belief before another.
