The operating point of a device, also known as bias point, quiescent point, or Q-point, is the DC voltage or current at a specified terminal of an active device (a transistor or vacuum tube) with no input signal applied. A bias circuit is a portion of the device's circuit that supplies this steady current or voltage.
A biased positional game [1] [2]: 27–42 is a variant of a positional game. Like most positional games, it is described by a set of positions/points/elements and a family of subsets (), which are usually called the winning-sets. It is played by two players who take turns picking elements until all elements are taken.
The point on the graph of the characteristic curve representing the bias current and voltage is called the quiescent point (Q point). In the above circuits the AC signal is small compared to the bias, representing a small perturbation of the DC voltage or current in the circuit about the Q point.

A bias tee is a three-port network used for setting the DC bias point of some electronic components without disturbing other components. The bias tee is a diplexer.The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF.
The center point (Q 1) is a point of unstable equilibrium (poles in the RHP), while the two outer points, Q 2 and Q 3 are stable equilibria. So with correct biasing the circuit can be bistable, it will converge to one of the two points Q 2 or Q 3 and can be switched between them with an input pulse.
Racial bias is baked, usually unintentionally, into games by those who develop them. This creates a recurring pattern of Black and Latinx characters being stereotyped or completely absent in games ...
