🔍 Key Concepts

• Impedance matching in a coaxial cable system (typical characteristic impedances of common coax types) • The purpose of termination resistors or inductors in a line-driver/line-receiver circuit • How incorrect impedance at point X would affect reflections and signal integrity on the coax line

💭 Think About

• First, think about the typical characteristic impedance of the coax used in most marine communication or data-link applications. Which value among the choices is closest to that? • Consider whether a resistor or an inductor would usually be used as the main termination element at the end of a coaxial transmission line for digital/line-driver circuits. • Ask yourself: is the magnitude of the component in each choice realistic for terminating a coax line at the frequency and application implied, or are some values clearly impractical?

✅ Before You Answer

• Identify the typical impedance of standard coax (e.g., 50 ohms, 75 ohms) and compare it with the resistor values given. • Decide whether a pure inductance with microhenry values would normally be used alone as a termination for a coax line in this sort of circuit. • Check that the value you select would minimize reflections and provide good power transfer between the line-driver and line-receiver.
