Phases can be determined by looking at the real and imaginary parts of the H(j ) function. Keep in mind, that in the complex transfer function model, the phase is given by: ( H(j ) = tan-1(H(j )) = tan-1(numerator) - tan-1(denominator) The following chart contains some useful values of tan-1.

Both real and imaginary parts should be zero: Real part = 0 → 4x - y+5=0. Imaginary part = 0 → 4y+x-2=0. Solving the two equations for x and y we obtain the real and imaginary parts of complex number z: x = -1.059 and y = 0.765. Therefore: z = -1.059 + j0.765. Example: crank-rocker four bar linkage.

Much of the time we find it convenient to consider the real and imaginary parts of this complex representation separately. Vout(() = VRe(() + jVIm(() where. VRe(() = V1cos(() and VIm(() = V1 sin(() Thus, we will also be keeping track of the real and imaginary parts of voltages and currents.
