Important parameters for linearity are integral nonlinearity and differential nonlinearity. Materials can have varying extents of linearity, homogeneity and isotropy. It is an indicator of tape uniformity and its linearity in analogue recording. Negative feedback trades gain for higher linearity (reducing distortion) and can provide other benefits. The concept of linearity can be extended to linear operators. This improved linearity of pointer deflection with respect to coil current. There is a tradeoff between range of motion, linearity of motion, and size. Because of linearity of determinant in every column, this map is linear. Closed loop control improves the linearity and stiffness of the system. Scale contributions to the error budget include linearity and slope (scaling factor error). The QBEE achieves good charge linearity over a wide dynamic range. The linearity of formula 31 with aspect ratio is evident. This is a fundamental consequence of the linearity and unitarity of quantum mechanics. MWI depends crucially on the linearity of quantum mechanics. This equation also is a direct consequence of the linearity of Maxwell's equations.
