I've never heard of a DC bias field. Can you provide some context?What is DC and AC bias? Are these two applied together to a circuit ? Also what is DC bias field ?
I never did know anything about audio tape recording. Too many subjects -- too little time.These terms used to be applied to audio tape recording to reduce distortion caused by the non-linear magnetic response of the replay head.

It would help if you told us the context to which this is applied.What is DC and AC bias? Are these two applied together to a circuit ? Also what is DC bias field ?
Nope, not replay. AC bias was used for tape recording.These terms used to be applied to audio tape recording to reduce distortion caused by the non-linear magnetic response of the replay head.

Hi MrChips, I first came across the DC bias field reading a research paper. The text contained :It would help if you told us the context to which this is applied.
The context for the DC bias field is from a research paper that mentioned the following :I've never heard of a DC bias field. Can you provide some context?
A circuit can be subjected to two different types of analysis. A DC analysis is where each point in a circuit has a defined and constant DC value This analysis establishes the DC operating point. A constant DC value in between a power supply value and ground is referred to as a DC bias (value). It is often constructed with a pair of resistors called a voltage divider. Once the DC operating point is established then a small signal AC analysis can be performed by looking at small signal deviations from the DC operating point.
I don't know that the term AC bias has any useful interpretation. If it does it's above my pay grade.
Correct, and so was DC bias.Nope, not replay. AC bias was used for tape recording.
