Z-PARAMETERS (open circuit parameters) The terminal characteristics of a two-port network, having linear elements and dependent sources, may be written in the s-domain as
V1=Z11 I1+Z12 I2 (1) V2=Z21I1+Z22 I2 (2) Z11 = V1/ I1 (for I2=0)


Gradient of a Scalar: • The gradient of a scalar field, V, is a vector that represents both the magnitude and the direction of the maximum space rate of increase of V. • To help visualize this concept, take for example a topographical map. Lines on the map represent equal magnitudes of the scalar field. The gradient vector crosses map at the location where the lines packed into the most dense space and perpendicular (or normal) to them. The orientation (up or down) of the gradient vector is such that the field is increased in magnitude along that direction.
