Termination

In high-frequency applications, reflections occur if signals are not properly terminated. Figure 7-5 shows a properly terminated signal while Figure 7-6 shows an improperly terminated signal.

To minimize reflection, use coaxial cable with matching characteristic impedance to the signal source. Terminate the other end of the cable with the same value terminator or resistor. For commonly used cables, RG59 has a 75Ω characteristic impedance, and RG58 has a 50Ω characteristic impedance.
