Broadband description of the copper cable transfer function

This report is describes the characteristics of two different copper cables, namely the coax cable and the twisted pair cable. By using the Maxwell equations we can describe the coax cable and the twisted pair cable with the Bessel functions. By these Bessel functions we can simulate the two secondary cable parameters, impedance Z and the propagation constant γ. The real part of γ represents the attenuation. The secondary cable parameter γ will also be used for calculating the insertion loss. When the insertion loss is calculated we can use the Inverted Fast Fourier Transformations (IFFT) to calculate the impulse response. The last part of the simulations is the calculation of the step response. This is achieved by integrating the impulse response. In the end of this report we will describe measurements of the coax cable over the whole frequency range. We will verify the simulated results with the measurements
