Figure 2 shows a plot of output (y) versus the input (x) of the system.A system with a constant k factor has a straight line or linear characteristic. A plot that isn't a straight line is termed ...

Using nonlinear Kalman filtering to estimate signals. It appears that no particular approximate [nonlinear] filter is consistently better than any other, though . . . any nonlinear filter is better ...

Examples of Linear Relationships Example 1 . Linear relationships are pretty common in daily life. For example, take the concept of speed. The formula used to calculate speed is as follows: the ...
